Chrissie Jackson

Chrissie Jackson was the ex-wife of Alan Jackson and the mother of Maria Jackson.

Chrissie and Alan divorced not long before Alan and Maria moved to Bannerman Road, and despite the separation, Chrissie continued to take an active role in Maria's life, often stopping by Alan's house unannounced. (TV: Invasion of the Bane)

Chrissie was involved in a relationship with a man named Ivan, which led to friction with Maria, who accused Chrissie of walking out on her family. This friction reached a head when Chrissie briefly moved back in with Alan and Maria during a brief estrangement with Ivan. (TV: Eye of the Gorgon)

Chrissie expressed a mixture of distrust and jealousy over Maria and Alan's relationship with their neighbour, Sarah Jane Smith. Her instinct appeared to be confirmed when Sarah Jane was suspected of kidnapping her adopted son, Luke, from another family, and it was Chrissie who notified the police. (TV: The Lost Boy)

She defeated Kaagh by swinging the heel of her high heel into his probic vent. However, as a side effect, she was electrocuted and temporarily knocked unconscious. Maria gave her gas, developed by Luke, to knock her out, making her supposedly forget about aliens. However, she later revealed that she remembered everything, but she didn't tell Maria or Alan as she thought they deserved a fresh start. The only one who knew this was Sarah Jane. (TV: The Last Sontaran)

Chrissie and Ivan planned to marry. Alan, Maria, Luke, Clyde and Sarah Jane were invited to their wedding. Maria and Alan wanted to come to the wedding and wished to see their friends from Ealing there again. (TV: The Day of the Clown)

Chrissie and Ivan planned to come to Washington DC during their honeymoon. Chrissie wanted Maria to show her all the best shoe shops in the capital. (PROSE: The Last Sontaran)

Timeline 1
In an alternate timeline created by the Trickster, in which Sarah Jane died in 1964, Andrea Yates saw Ivan snogging Lorraine Groom outside the Conservative Club and told Chrissie Jackson about it. Chrissie Jackson dumped Ivan because of this. Chrissie needed money so she started to work at a supermarket and even wear a supermarket uniform. Maria thought it looked odd on her. Chrissie later met Ricardo and dated him. Maria Jackson had already met Ricardo plenty of times. (PROSE: Whatever Happened to Sarah Jane?)

Timeline 2
In the alternate timeline created by the Trickster, in which Sarah Jane died in 1964 and Maria was also taken out of time and space, Chrissie and Alan still divorced but Chrissie had no memory of ever having a child. Despite this and their divorce, she and Alan were still close and had a mutual friend in Andrea Yates, the neighbour who replaced Sarah Jane in the timeline. (TV: Whatever Happened to Sarah Jane?)

Personality
Chrissie's personality tended to be brash and rude at times, although she exhibited tenderness towards her daughter and continued affection for her ex-husband. (TV: Eye of the Gorgon, TV: Whatever Happened to Sarah Jane?, TV: The Lost Boy) She also expressed continued scepticism about the existence of alien life, despite worldwide events and her own face-to-face encounter with a Graske. (TV: Whatever Happened to Sarah Jane?) She also took the news that aliens existed and her daughter fought them much better than her ex-husband. Chrissie was also unafraid of danger, as she willingly rushed off to find Maria when she was fighting the Sontaran Kaagh, and immediately charged into the fray upon seeing him threatening Maria's life. Chrissie was also a lot cleverer than she looked, as she was able to remember the sole weakness Sontarans had despite having only heard it for a few seconds and strike it with pinpoint accuracy.

She had a tendency of calling Sarah Jane a number of different names, such as "Mary Jane", (TV: Eye of the Gorgon, The Last Sontaran) "Bobby Sue", (TV: Whatever Happened to Sarah Jane) "Sally Jane", (TV: Eye of the Gorgon) "Sally Anne", (TV: Revenge of the Slitheen) "Contrary Jane" (TV: The Lost Boy) and "Calamity Jane".
