Leah in the second season finale

The idea that she's "the one" or whatever we're supposed to believe is just ridiculous. She was arguably the most useless in terms of survival on the island and suddenly in captivity she's Keyser Soze. By the last day on the island she was ready to attempt to kill herself (again) while having some fantasy with Ben Folds. Plus I had to laugh at that montage with her walking away smiling showing us a bunch of things that we basically already knew happened.
