Tom
Honey I don't know. Yeah you're dead in their world, but will they even remember you when the door closes and we go back to the island? Pandora-Jake might never know you were here. For all we know our Jake could be their Jake too.
I have no idea what I would do if I were in a similar situation. I've got your back whatever you decide to do. Are your friends at the base? I guess I should probably use my maiden name when I'm there rather than Sully, otherwise it would seem pretty strange to have the super pregnant lady claiming to be Tom Sully's wife when he's dead.
