Child's Play Theories

Chucky and Sarah

In Curse Of Chucky,in a flashback it is shown that Chucky(human) had an obsession with Sarah. But,it is also said in other movies that Chucky and Tiffany dated while he was human,well,If that is true then why the heck was Chucky so obsessed about having a family with Sarah if he had Tiffany(BTW him and Tiff are a cute couple) here is my theory:

Chucky and Tiffany had a big fight(and in that fight Tiffany ended up saying "there is no us") Chucky packed his stuff and went to Chicago,when he was there he met Sarah and her family.

So he decided to start over and start a family with Sarah,so Chucky killed her husband and kidnapped her,he did think about Tiffany but thought that she probably moved on too. Then when Sarah called the police Chucky said "you told them about us" because he thought Sarah actually loves him. Then,when she said"there is no us" he got flashback of Tiffany saying that and thought about how no one was gonna love him and stabbed her stomach to get quick revenge on her.

In Bride Of Chucky,he realized that Tiffany never moved on,she never stopped loving him. And that's when he also realized that he loves Tiffany too.

So that's my theory on why Chucky even had a thing on Sarah(Well,really I don't think Chucky loved her to begin with,she was more of,I can't have Tiffany so I guess your my next option)
