Cole thinks she's lying, especially when she can't answer his question about whether she's in love with Miles or not. She can love him in time, she points out. She insists it was the right thing to do and it was her choice. Cole decides that she was either drunk or hurt in the bombing and the entire thing is an insult to his dad's memory, which hurts Marty.
