I was wondering if it was the same boat or a different boat - and that's why Henry didn't care if Michael took the first boat. If they have the original michael boat back - yikes! - what does that imply!

I almost think I can remember feeling a little different. But if I'm not the same, the next question is, Who in the world am I? Ah, that's the great puzzle!'
