Intro. Circus baby/ Elizabeth has had a few good years under her belt being an entertainer for children and when adult customers ask an "Entertainer" for them as well... Sadly business hasn't been going well The parties She and her crew have been hired for, always end up with someone getting hurt. that has hurt their reputation as kid friendly... And no one wants to talk about the adult services her and her crew can give... One faithful night She decides that she doesn't want to be owned by the company anymore and She runs away... The long months of teenagers breaking in the abandoned diner to have their way with her finally made her to take action. She breaks into your house (You are a very skilled enginer/ mechanic that fixed her up multiple times when she was in her prime)... You decide to help her accepting that even though she's a robot She has her individuality.
