WHOOSH to Jack in a nice, comfy bed when the phone rings and wakes him up. It's his assistant reminding him of his schedule changes. Jack gets up and goes into the bathroom.

At the beach, Juliet talks to Jack. He thinks it's food poisoning. Juliet disagrees. She makes him lift his shirt, and she presses on his side. Jack grimaces in pain.

Startled, Jack turns and sees Christian Shephard sitting in the waiting area. Then a co-worker comes around the corner and asks if everything is okay. Jack jumps, thinking he was the only one there. When he looks over, the chair is empty. He asks her if she could write a prescription for clonazepam. He says he's been having a lot of nightmares and trouble sleeping.

Kate tells him to stop, to let it go. But Jack wants to know. Finally, Kate says she was doing something for Sawyer. She made him a promise. Jack is hurt. Sawyer's not there. He made his choice and chose to stay. Jack is the one who is there. He's the one that saved her. Kate tells him he can't do this. She can't have him around her son.

But Jack turns and walks out.
