If I could be Sun for a day I would......

Know that our raft boys are in trouble because I already saw the finale episode and warn everybody and send a rescue team to save them from the traitorous waters! Then, I would send another rescue team to rescue Walt who has been kidnapped by the Others. Then, after everything is calm, I would take a stroll down that long path by the ocean with Jin!! ;) ;) ;)

.....I would beat up Danielle for stealing Claire's baby!!! (and hope she doesn't hurt me too badly because she's a wild/crazy lady!!!)

I would pick Jack's brain about all kinds of medical stuff in case something shouls happen to him so I could pick up the "doctoring" for the Lostaways.

I would go to the Black Rock and find the radio tower that is supposedly near it.

Or I would destroy all of the heroine so Charlie wouldn't be able to get to it.

Or I would try to walk around the whole island and see if I could find the "Others" lair.
