At the part when everyone including Melissa is at Aunt Meg's house, they listen to Jonas awhile then turn the t.v. off. But later on when they're rushing to leave, the t.v. is back on, and everyone is at the table except for Joe but she's in the shower. OOPS!
They were all done eating. They started watching T.V. again. Is that a big deal? There is a point where Jo is taking a shower. between then and then there is possible time where they could have turned on the T.V. anywhere between then and there.
