Who's gonna kiss Some combo of the love quadrangle (pictured) is the easy answer, since two of them leave the island and two appear not to, but what if it's a more shocking pairing Say, Sayid and Juliet Or Sawyer and Claire Or (gag) Kate and Ben!

Is Aaron's mummy going bye-bye With Aaron now living with Kate and calling her mama, one could assume that Claire is either a) dead or b) back on the island wielding the least effective Amber Alert ever. Is a tender sign-off in her future

How did Alex end up with Ben Poor Alex grew up thinking Ben was her father. How did that "happen" And isn't it a little strange that it took a hardcore jungle survivalist like Rousseau 16 years to find her

Is Jin really dead We saw Sun bring her newborn daughter to Jin's grave, a grave that showed Jin's date of death as September 22, 2004, the date of the crash. Did he really die, or is it some elaborate Oceanic Six cover-up

Who are the bad guys Ben is fond of saying that he's one of the good guys. More recently, he's pointed an accusatory finger at Charles Widmore (Alan Dale, pictured), Penny's dad, as the guy who faked the crash of Oceanic 815.
