So why WAS the wife at the hotel????
It's didn't look to me like the wife and the other guy were actually having a full blown affair, though some people on this board seem to think she was already cheating on her husband. When the wife was at the restaurant having a conversation overheard by the brother, all she did was talk about her relationship. The other guy was playing the sympathetic ear (buying his time of course). Yes, they probably both wanted to have an affair, but it didn't sound like it had happened yet.
Then they were at the hotel and the guy was getting ice. When they broke into the hotel room, I saw no signs that a sexual encounter had taken place and nothing that made it look like they were going to start in the next 5 minutes. So then why was she at the hotel to begin with? I kept waiting for there to be some other explanation she would give as to why her and this guy were in the room.
Yes, you can say they were going to have sex, but it didn't remotely look like they were going to start. I know the movie is full of these inaccuracies, but I'm really curious as to what was going on in that room when it clearly didn't look like there was anything going on.
