Can she even take the kids???
When Graysmith comes home and sees the note saying that his wife took the kids to her mom and not to call. Can she even do that? Is it legal?
Regardless, the Graysmith family makes no sense since we see him with 1 child and he tells him he'll he spending the night with Mom and Aaron and the kid looks upset. For someone who is watching the movie for the first time and doesn't understand the case or characters going in it implies Aaron is the step dad or the moms boyfriend and he has a new step brither he's not interested in seeing.
However, it's just the kid going to be spending the night with his mom and Aaron his little brother.
Graysmith even tells Avery that he's divorced and 2 kids. We see years later Graysmith and Melanie with his 2 boys and a baby girl.
So technically Melanie only has custody of the baby girl but zero authority on the 2 boys. It's almost like a child abduction.
