You have to love The Sentry. At least he's reliable. Whenever something happens, he gets all emotional and flies off into space. It's like a checklist: Osborn: Crazy Asshole. Cyclops: Massive Tool. Wolverine: Snikt Snikt Bub Bub. The Sentry: Still Useless.
As an aside, nothing better happen to Emma, or that island is going to sink again.
