"I took them from the laundry":P not supposed to be funny but it cracks me up every time.
"What have you done with your brother???"

I never got how the mom figured it out just by seeing them hug. I know he runs his hand down her back, but still what a guess.
They were pretty affectionate with each other already, so yeah, I don't know why she jumped to that conclusion. Woman's intuition, I guess?
They were pretty affectionate in the beginning of the film too. I think they had a natural attraction to each other...
