I'm not positive but I think when Jack called David's phone he said something like if you are at your mother's house and something about her being out of town.
your right...He said he was gonna drive over to his mothers house.
scratch the living with grandma notes. wow i must be tired lol
Jack left David at his appartment and when to his mother's house to look for his father's will. When he returned he found David missing and then went to look for him at David's mother's house (ie David's main residence). Later when Jack found David, David stated that he was basically able to sneak off becasue Jack "had gone to grandma's" ie Jack had went to Jack's mother's house not the house that David lives in with HIS mother.
that clears it up for me ..thanks
so Mother is out of town ...... Business trip?
Penny in England?
