So a child welfare worker just....
gives out Andy's location over the phone? Especially to an "Uncle Charles"?
Also, good thing for Chucky that he ended up with the man (possibly/likely) the only man who is carrying files on Andy.
Just a tip, if you are burying a (doll's) body, make sure not to do so right underneath a swing set. A taller person's feet may drag along and eventually uncover it.
And why was it that every time Chucky was on someone's back, they were unable to move? He was still a doll after all.
