Corrected entry: When Jimmy and Brad are talking to Emma (the deaf girl) near the end of the episode, Brad translates Emma's sign language for Jimmy, but when Jimmy talks, Brad makes no hand signs for Emma. Therefore, she shouldn't be able to understand what Jimmy is saying, yet she replies. She can't be lip-reading, or else she would have understood what Lily or Henry was saying upstairs in Jimmy's room (you could see from her reactions that she didn't understand either of them).
Corrected entry: When Sean is telling Eddie about what happened with Lily, he starts out by explaining that she wanted to go on a ski trip. But in the flashback where the family received Sean's mother's money, Sean told Lily that she wasn't going on the ski trip, and Eddie was there. So he heard this and actually knows already about Lily being mad about not going on the trip.
Corrected entry: In the scene where Sean, Eddie and Walt are playing pool, right after Eddie tells Sean "Women say they don't want you to get them anything, 'cause they want you to want to get them something, it's proof of your desire to please them", Sean calls Eddie by his real name and says "Kevin I'm terrible at picking stuff out for her, you know.".
