With their 1st child Ollie 14 months old ,Janet decided to have another baby so George impregnated her. Due to the fact the George is Ultronian Janet's labour lasted only a day and George came with her to hospital. George used an Ultronian Technique to help with the labour where he pushed hard on Janet's bump shooting Cassie out right into the Midwife's arms. They then went back to their flat, where she was introduced to her brother Ollie however he didn't like her at all and became jealous of her.
Due to her foreseeing that she would win all her arguements with him, George gave up trying to control her much to Janet's Dismay. When George and Janet visited the Northolt Health Centre, she told her parents that she foresaw Ella's death, shocked by this Janet told George to keep an eye on Ella to make sure she didn't die however Cassie then also foresaw Stanley's, Arnie's and Tyler's death but strangely she didn't foresee Doctor Crispin's death.
She then foresaw the death of everyone on the Northern Hemisphere which explained why she didn't foresee Piers death as he was due to star on I'm a Celebrity Get Me Out Of Here. As Thermoman prepared to evacuate everyone from the Northern Hemisphere Ella suddenly appeared to have died but it turned out she was actually asleep. This revealed that Cassie made a mistake as she didn't known what sleeping meant, George was very embarassed and decided to take her back and have a new baby but Janet convinced him not to.

Cassie put her Foresight ability to bad use, saying that something bad will happen if she doesn't get dolls. (Illegal Aliens)
To save up for a doll's house she took up various telephone jobs from her cot from directory inquiries to speaking clock. Jealous Ollie soon puts an end to her money making, however, by tricking her into saying the wrong thing at the wrong time in front of Janet, who promptly confiscates her phone.
When Cassie's grandmother Ella became a Justice of the Peace and a Magistrate. Ella started forcing her authority on Janet and George making sure they took better care of their children. Unfortanutely Arnie set up a 14th month birthday party (equivalent to a human 18th birthday part) with lots of Booze and Cigars, when Ella and Stanley found Ollie drinking and smoking in the flat they took him and Cassie to their house to take care of them. Being with human grandparents soon regressed Cassie to a normal Human baby unable to talk, unfortanutely George was unable to make her speak. However Ollie managed to save the day by messing up Ella's house (including putting Cassie on a lamp) to convince a social worker that Ella is a poor carer, Tyler was able to teach Cassie to speak again however she spoke with a Liverpudlian accent due to Tyler being from Liverpool. (Cassie Come Home)
Arnie decided to give the Sunday's a treat by giving them a computer. George decided to search the internet to see if it was safe for Ollie and Cassie, however using an Ultron mind control device he mixed Janet,Piers, and Tyler's personality. Even though George tried to act normal around Janet (Who was in Pier's body) Cassie had to tell Janet because she couldn't "stand the breastfeeding". (Brain Drain)
