Charlie Smith

"Charlie Smith" was the Prince of Rhodia, and the last of his species, the Rhodians. Before the loss of his planet, he was heir to the throne, son of the King and Queen. (TV: Co-Owner of a Lonely Heart)

He was rescued by the Twelfth Doctor during a war with Shadow Kin, and taken to Coal Hill Academy in September 2016, posing as a 17-year-old human student from Sheffield. (TV: For Tonight We Might Die, Co-Owner of a Lonely Heart)

Charlie lived with Miss Quill, and later Matteusz, at 1 Wellington Road, London. His postcode was N1 0HR. (TV: Co-Owner of a Lonely Heart)

Personality
Charlie was gay. April described him as weird, saying he didn't know anything about pop culture. To her, he'd have to be either alien or Amish. (TV: For Tonight We Might Die)

Though he hadn't been on Earth yet for very long, Charlie had watched The Vampire Diaries; he found everyone on it very attractive. (TV: For Tonight We Might Die)

History
Charlie was born and raised on the planet Rhodia. He was a prince, and ruled over his people for several years with his mother. (TV: For Tonight We Might Die)

Charlie's family never saw Charlie as someone worth bothering combining with, instead as a valuable piece of property to be used for the good of the country. (TV: Nightvisiting)

At one point, the Rhodians went to war with their planet's other race, the Quill. The Quill's lead freedom fighter was enslaved to serve Charlie and be his protector.

The Shadow Kin attacked and killed every Rhodian and Quill, including Charlie's mother. (TV: For Tonight We Might Die)

Charlie and his servant were then rescued by the Twelfth Doctor, who took them to Coal Hill Academy. Pretending to be from Sheffield, Charlie's servant took on the name of Miss Quill and posed as a teacher, while Charlie posed as a student in Year 12. (TV: For Tonight We Might Die)

He and Miss Quill lived in an apartment situated on the Central line of the London Underground. (PROSE: Joyride) Their address was seen in report from The Governors as 1 Wellington Road, N1, presumably placing them somewhat north/northwest of Shoreditch.(TV: Co-Owner of a Lonely Heart)

He was asked out by April but rejected her. He noticed the burn marks on the corridor floor after Kevin Williams disappeared and deduced that they were from Miss Quill's gun. He prevented April from firing the gun (which would have killed her) causing her to share a heart with the Shadow Kin King, Corakinus.

Charlie asked Matteusz out for the Autumn Prom, and they attended it together. He wielded Miss Quill's gun when the legion of Shadow Kin attacked, but it was later destroyed. (TV: For Tonight We Might Die)

He encountered a dragon monster that ate his head teacher, Mr Armitage, and saw the dragon pull Coach Dawson, who had the dragon's mate trapped inside his skin, through the rip in space-time. (TV: The Coach with the Dragon Tattoo)

One Tuesday, Charlie, Tanya and April saw Amar Sai on the roof. They managed to prevent "joyrider" Viola Cummings, who was controlling Amar's body, from running a trial suicide at his expense. Charlie was later attacked by April, Tanya and Matteusz, who's bodies were all being controlled by Joyrider leader Garry Fletcher via stolen alien technology after he learned that Charlie and Quill were aliens. Charlie escaped and all three were returned to their bodies. (PROSE: Joyride)

Some days later, Matteusz arrived at his home, having been thrown out by his parents for his relationship with Charlie. Charlie offered him residence, and the pair ended up having sex. When the Lankin arrived in his apartment, he caught a glimpse of them trying to form his parents but they failed.

Downstairs, Miss Quill ordered him to drive a screwdriver through the hand of her sister, which in actuality was part of the Lankin. The Lankin confessed to feeding off of Tanya Adeola before disintegrating. Charlie, Matteusz and Miss Quill rushed to Tanya's. They tried severing the smaller roots but they kept reforming. Charlie and Matteuz managed to sever some roots before Miss Quill destroyed the trunk with a double decker bus. (TV: Nightvisiting)

When Matteusz became intrigued about the ornate box in his bedroom, he showed him what it contained and explains the legends and fairy tales associated with it. He explained to him that it could be used as a weapon as the souls it contained, either to kill or to inhabit the enemy, and Matteusz didn't like this as it's use would initiate a genocide. Because of this reaction Charlie ignored Matteusz's concerns about the killer petals. When Ram called Tanya after April started acting strangely, he witnessed April travelling to the Shadow Realm.
