Chrissie Jackson (Andrea Yates's universe)

Chrissie Jackson lived in a world in which Sarah Jane Smith died as child in 1964.

Biography
Due to the meddling of the Trickster, Andrea Yates's world was everchanging, and so Chrissie lived in two similar but alternate timelines; one with her daughter, Maria Jackson, and one without.

Timeline with Maria Jackson
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 without Maria Jackson
Chrissie and Alan still divorced but Chrissie had no memory of ever having a child. While Alan wanted kids, Chrissie never did. She stated that she hadn't got a maternal bone in her body. Despite her reluctance to have children, Chrissie chastised that maybe if they had had kids, her and Alan wouldn't have split up.

She and Alan remained close, despite their divorce, and shared a mutual friend in Andrea Yates. On the day Alan moved into 36 Bannerman Road, Chrissie and Andrea both helped him to unpack.

Chrissie chose to attend Andrea's birthday party. When Clyde Langer turned on the television, Chrissie became aware of approaching meteor K67, but the news stated that there was no need to panic. Upon hearing that the missile strike had failed to stop the meteor, Chrissie and Clyde ran outside. Chrissie realised that there was no way of stopping it. (TV: Whatever Happened to Sarah Jane?)
