You were juniors sister and your uncle (jakes dad) had just died so jake was staying with you, your parents and your brother. You didn't mind though because you always got along well with jake.

you decided to hang out with jake since you were bored so you walked into his room to see this doll he's been obsessed with (chucky) talking and moving, you stood there in shock for a moment until jake noticed you standing there and the doll looked at you.
