I do find myself wondering who is going to be investigating the ever growing pile of corpses at that resteraunt: Anna Lucia or Detective Ford and his sidekick? And if thet will correctly deduce what went happened. (Though 'Detective Ford' might have his hands full with Kate).
One other item there: in the original timeline, when Jin and Sun were actually married, was Jin still being sent unwittingly to his death by his father in law? Or was the watch (and money, if any) intended for something ... more legitimate?
As to Mikhail, that guy turned out to be almost unbelievably tough the first time around. If any of those guys on the resteraunt floor pulls through, he'll be one of them.
One other little item about Sun-on-the-island speaking only Korean...I wonder if this could be an indicator that the timelines are starting to merge? Because, the flash sideways Sun knows all of about four words of english...
