But after this week's finale, we can't help but wonder: Is it possible that Melissa is the one who's trying to come between her husband and his sister? At the end of the episode, Melissa quietly told Joe that it was Teresa who set her up. Then, as they were driving out of the parking lot, we heard her whisper to Joe to roll down his window and yell "Shame on you!" at Teresa. When he started shouting something different, she reminded him to use the word "shame," as if she knew that would really push Teresa's buttons.
We don't know if putting a wedge between them was her goal, but she clearly does get involved in their relationship. Maybe when Teresa claims that Melissa tries to turn her brother against her, she's somewhat right?
