After a nightmare, Oliver can't hold back what happened to him while on the island anymore and goes to the one person he knows will always listen and answer the phone when he calls, even at two am. Sneak peek: "Ollie, why did you call me?" She asks her ex-boyfriend, using the nickname she had given them when they were five years old. Oliver sighs again on the other end of the phone. "Because...because." he gets out. "After everything, I've put you through, you still answered the phone at 2 am, knowing it was me calling." He says knowingly.
