Who was the other kid in the family?
The reason i ask the question is this:
We know that Rusty is sleeping in Audrey's room due to the grandparents being over the house. Later in the movie we see them in bed together and then switches over to the grandparents sleeping in Rusty's room. It's weird because Rusty has bunk beds in there and the grandfather is sleeping on the top bunk while the grandmother is on the bottom bunk.
I find it strange that they would have bunk beds when there is only one child sleeping in that room...so who's the third kid lol
