Inside the Stabler Home: Kathleen & Elizabeth's Room
In season 8, it appeared that Kathleen and Elizabeth shared a room (while Dickie had his own room as did Kathy; Maureen did not appear in this episode she may have moved out at that point). But could they have been at Kathy's mother's house?
It doesn't appear that Elizabeth shared a room with Kathleen but then again the whole room wasn't shown- Elizabeth's bed could've been on the other side? Then again, this scene could've taken place very late at night (around midnight) so Elizabeth could've had her own room for sure or was sleeping elsewhere to give Kathleen her space after her wild night out.
