River Song

River Song, (born Melody Pond), was a mysterious archaeologist and a convicted murderer.

She was the daughter of Amy Pond and Rory Williams, and shared a close and somewhat romantic relationship with the Doctor, becoming one of the few people to learn his true name. She occasionally used the title of doctor and later, professor. Like Melanie Bush and Charley Pollard before her, she was an example of the rare companion whose timeline was not synchronous with that of the Doctor.

Birth
Melody Pond was born on Demon's Run to Amy Pond and Rory Williams after her mother had been kidnapped. Shortly after birth, Melody was replaced with a Ganger. She was taken from Amy by Madame Kovarian to be used as a weapon against the Doctor; chosen for this purpose because she had traces of Time Lord DNA mixed in with her human DNA, as a result of being conceived in the TARDIS. (DW: A Good Man Goes to War)

Adventures with the Doctor
River Song mentioned that when the Doctor first met her, he knew absolutely everything about her and her identity. (DW: The Impossible Astronaut) Some time prior to the Battle of Demon's Run, River was imprisoned in the Stormcage Containment Facility for murdering someone she described as, "A very good man. Best man I've ever known". (DW: The Time of Angels / Flesh and Stone)

Demon's Run
After River was taken by the Doctor for her birthday to the last Winter Frost at the Thames in 1814. There, Stevie Wonder unknowingly performed, before being taken back to his original time. Upon returning to Stormcage from this adventure, River encountered Rory in his Roman uniform. She refused his request when he asked her to come to their aid at Demon's Run, knowing she could only be there for the "final moment".

River travelled to meet the Doctor, Amy, and Rory at the end of the battle of Demon's Run. It was here that she revealed her true identity, first to the Doctor. She then Rory and Amy that their daughter would be safe, that the Doctor would find her and told them who she was.

The Church soldier Lorna Bucket gives Amy a Prayer Leaf with her daughter's name sewn into it.

"It's your daughter's name in the language of the forest ... 'cept they don't have a word for Pond. 'Cause the only water in the forest is the river. The Doctor will find your daughter and he will care for her whatever it takes. And I know that. It's me. I'm Melody. I'm your daughter." (DW:A Good Man Goes to War)

Silence in America
After receiving an invitation containing geographical co-ordinates from the Doctor, River escaped from the Stormcage Containment Facility, in order to meet him in United States of America in 2011. River met the Doctor, Amy, and Rory in a cafe in the middle of the Utah desert. After reminiscing with her about Easter Island and Jim the Fish, The Doctor took all of them to a picnic, where they saw him murdered by someone wearing an astronaut's space suit. River, Amy, and Rory cremated the Doctor's body in a 'Viking Funeral'. They returned to the cafe and discovered another Doctor, approximately two hundred years younger than the one they had seen die. (DW: The Impossible Astronaut)

River helped the Doctor defeat the Silence by using the Silence's brainwashing of humanity against them. At her request, the Doctor returned River to Storm Cage where she kissed him goodbye. From his shocked reaction, she realised that from his perspective it was their first kiss, and she would never kiss him again. (DW: Day of the Moon)

Opening of the Pandorica
The TARDIS rerouted a phone call meant for the Doctor from Winston Churchill to River. She escaped from her prison to try and save the Doctor from a deadly prophecy of the TARDIS exploding. After obtaining a Time Agent vortex manipulator from Dorium Maldovar, River travelled back in time to the Roman era of Earth where she met the Doctor and Amy.

They proceeded to Stonehenge where they searched for the Pandorica. After locating it, they discovered that Stonehenge was transmitting a signal, bringing an alliance of the Doctor's enemies to Earth. The Doctor managed to convince the assembled aliens to back away for a time, and sent River to bring the TARDIS to him. However, the TARDIS brought River to Amy's house on the 26th of June, 2010. When River told him the date, the Doctor realised the TARDIS was about to explode and urged River to escape. Instead, she found herself trapped as the TARDIS came under control of an unknown external force and started to explode. (DW: The Pandorica Opens)

Inside the TARDIS, River was stuck in a time loop of the first moments of the TARDIS explosion. The Doctor, using the vortex manipulator River had acquired, was able to retrieve her and bring her back to 1996. Upon joining the Doctor, River killed the Stone Dalek that was hunting them.

After the Doctor restored the universe to life, erasing himself in the process, River left her now blank TARDIS-shaped diary with Amy Pond on her wedding day in 2010 so that she could remember the Doctor back into existence. After a brief encounter with the Doctor, River teleported away with the vortex manipulator. (DW: The Big Bang)

Crash of the Byzantium
At some point, she was put in Father Octavian's custody. If she were to carry out the mission assigned to her, she would earn her pardon. While working for Father Octavian, River was sent to be a guest on the Byzantium ship. She infiltrated the lower levels to find the Home Box, into which she carved the message "Hello Sweetie" in the Old High Gallifreyan language to attract the Doctor's attention. Leading the Doctor to Alfava Metraxis, she helped him defeat an army of Weeping Angels, who had been awakened in the planet's Maze of the Dead. (DW: The Time of Angels, Flesh and Stone)

Darillium
At some point, River earned her pardon and received a surprise visit by the Doctor. He took her on a trip to Darillium to see the Singing Towers. Unknown to River, the Doctor knew her death was impending, and gave her an upgraded version of his sonic screwdriver. This would be the last time that River saw "her" Doctor. (DW: Forest of the Dead)

The Library
River, now a professor, was chartered by Felman Lux to lead an expedition to the Library in order to discover exactly what had happened there a hundred years earlier, when a cryptic final message had been sent: ">>> 4022 saved. No survivors <<<". Anticipating trouble during the expedition, River summoned the Doctor by sending him a message via psychic paper. The earlier version of the Doctor who turned up had not yet met her. Though bewildered, he agreed to help River and her team.

River still had her TARDIS-shaped diary describing her travels with the Doctor. Although she tried to use it to discover where the Doctor was in his timeline, she realized that she was with a much younger version of the Doctor, who did not know who she was, nor did he trust her. As the situation against the Vashta Nerada deteriorated, River realised she must prove to the Doctor that she was someone he would come to trust completely and, with profuse apologies, whispered his true name into his ear. The Doctor was stunned by this information, and River had won his trust.

River physically died when she chose to sacrifice herself in the place of the Doctor in order to save Donna and the other 4022 people trapped in the Library's computer. She pleaded with him to not try and change history, not to change one moment of what had/would come for them. (DW: Forest of the Dead)

After saving all the trapped people, the Doctor realized his future self must have given her his sonic screwdriver for a reason. Inside he found a data chip called a "Neural Relay", which contained River's Data Ghost. The Doctor saved her by uploading her into the virtual world contained in The Library's data core. CAL, the library's data core, controlled by a human girl (Charlotte Abigail Lux, or CAL) wired into its mainframe CAL had also saved the data ghosts of all of River's dead archaeological team, in the process giving her company in the virtual world. River would go on to take care of the two virtual children and Charlotte in the virtual world, reading out her diary of her life with the Doctor and how "everybody lives" when the Doctor comes to call. Her story ended with her telling the sleeping children sweet dreams. (DW: Silence in the Library / Forest of the Dead)

The Doctor would later remember her death when Davros reminded him of the people who had died in his name. (DW: Journey's End)

Personality
River had a feisty and cheeky personality. She often enjoyed showing off her knowledge in front of the Doctor, particularly knowledge of him and his personality. She would often use the word "spoilers" in reference to her knowledge of the Doctor's future, or his knowledge of her future. River was also persistent at keeping secrets from the Doctor, especially anything which could change the future. This included keeping her personal diary from him.

River was devoted to the Doctor and cared very much for those around her such as her mother and her team in The Library but she could also be merciless, killing the Stone Dalek after it had shot the Doctor even though it pleaded for mercy when it realised who she was. She also taunted the Dalek before killing it by ordering it to beg for mercy. River Song was shown to be very confident in her abilities, intelligence and sexuality. She was often flirtatious but was serious when the situation called for it.

River was also willing to sacrifice herself and took the Doctor's place when he attempted to release the people who were saved within the giant computer that controlled the Library. She pointed out that if the Doctor hooked himself up to the computer it would incinerate both his hearts and ensure that he would be unable to regenerate. In order to prevent the Doctor from killing himself, River actually knocked him out and then handcuffed him before hooking herself up to the computer. Just before her death she comforted the Doctor by saying that although it was her last meeting with him it was his first meeting with her and therefore he would see her again. She was also willing to sacrifice herself to close the Time Field on the Byzantium to stop the Doctor from doing it, until the Doctor told her it wouldn't be enough.

Other information

 * River Song seemed to take shorter trips with the Doctor, living a more or less normal life between trips, rather than having one extended trip with the Doctor and never seeing him again after parting ways.
 * River Song was a skilled TARDIS pilot (with very different techniques from the Doctor). She mentioned that she "learned from the best," but joked that the Doctor wasn't available that day. (DW: The Time of Angels) Later she stated that the Doctor had indeed taught her. (DW: The Pandorica Opens)
 * River appeared to have knowledge of Time Lord anatomy, including knowledge of regeneration. She indicated that destruction of both of the Doctor's hearts could be a circumstance after which regeneration was not possible. (DW: Forest of the Dead). She also understood that if the Doctor died before his regeneration cycle was complete, he was dead for good. (DW: The Impossible Astronaut) This could be due to her having traces of Time lord DNA in her DNA.
 * River Song had the ability to write in Old High Gallifreyan, but it is unknown where she learned this. (DW: The Time of Angels, The Pandorica Opens)
 * River possessed pictures of all the Doctor's incarnations (DW: The Time of Angels), though she did not know the order of the Doctor's incarnations.
 * River was sentenced to prison for murdering a man described as "a hero to many" and whom she called "A very good man. Best man I've ever known". Octavian felt that the murder victim's identity was something that the Doctor "really [didn't] want to know." (DW: Flesh and Stone)
 * Before his death, Octavian told the Doctor that "You think you know [River], but you don't. You don't understand who or what she is." (DW: Flesh and Stone) These are later explained in DW: A Good Man Goes to War. River has traces of Time Lord DNA due to her parents "beginning" her while on board the TARDIS; she is Amy and Rory's daughter.
 * River told Rory that she and the Doctor were meeting in reverse order and that every time she met him, he knew her less. She feared the day when she met a Doctor who did not know her. (DW: The Impossible Astronaut)
 * Generally, River met the Doctor in reverse order respective to their timelines. This was not always the case, as River once met a version of the Doctor who had shared an adventure to Easter Island and a meeting with Jim the Fish.
 * Humorously, the conversation at the end of DW: The Doctor's Wife implies River was conceived on a bunk bed. When asked about this, both Steven Moffat and Neil Gaiman independently and simultaneously acknowledged this, joking about the possibility of the ladder. They later suggested they had accidentally canonized this by agreeing on it at the same time.

Behind the scenes

 * Except for a flashback, River Song has only appeared in two-part stories that have been written by Steven Moffat.
 * In a recent interview for a short video about the Eleventh Doctor's companions, Alex Kingston stated that River Song has encountered many incarnations of the Doctor and that the Doctor "sends her into his past, where he knows he needs her expertise". Arthur Darvill stated that Kingston had been told more than anyone else about who River really is.
 * The episode A Good Man Goes to War revealed that River Song (born Melody Pond) was actually the daughter of Amy Pond and Rory Williams, and possessed Time Lord DNA as a result of being conceived whilst the TARDIS was travelling in the time vortex. It was implied in the episode, through the use of flashbacks and speculation by characters that Melody might be able to regenerate, that the little girl is Melody/River; however, this has not been explicitly stated on screen.
