As long as chucky remembers what happened to him during those 3 hours.
Chucky is smarter than you think. He gonna come out of the prison cell and be sneaking to get some weapon like some gun or knife and when the guards saw it so Chucky gonna play and these guards gonna think you throw it out of the cell. When Chucky got a gun and back to your cell like and shoot you and having polices think that you committed suicide while Chucky plays dead and .
So, I don't want that f*ck doll Chucky......so don't underestimate him.
