I think I may have messed up.
I had saved after I found Li, and was just exploring and things when I had gotten mauled by some starfish and a big centipede type monster. Needless to say I died, and was respawned at the save rock in Li's cave.
Problem is now, there is
another Li swimming around with the helmet on.

It isn't a really big deal because I have another save file before finding Li and can just go back to that, but I don't want to make the same mistake twice.
Oh, and sorry for the blurry screenie.
