Unspoiled! The Constant: Lost

BOOOOONE.  I mean, Locke goes on a vision quest and his guide is Boone. He is instructed to save Eko FROM A POLAR BEAR, which he and Charlie successfully do. Elsewhere, Desmond is running around naked and seeing the future. And there's these two randos who seem to think they're part of the group, but we've never seen them before. Shut up, Nikki.
