so some of don't think Juliet actually removed his appendix... but if not what did she do?

and I think Jack was full of crap about the discharge thing.

I'm sure he was full of it when he was talking about the discharge but I can understand how he'd want to calm Kate's fears. It's what he does. He knows that he's in trouble physically. He'll just try to push on through.

She told him she knew he was lying.
