Miles was part of my biggest season 6 theory that never came to pass, and I hate it.
The Temple episodes of Season 6 established a bunch of rules about interacting with the Man in Black, how if he talked to you or you looked into him you'd be under his power or whatever. You couldn't kill him if you interacted with him basically. We had those rules in place pretty much just for Sayid ad Claire for a few episodes in a dumb sub-plot, but you know what would've been really great?
Miles, who managed to barely dodge encountering the monster all season and was surviving with Alpert and Lapidus off on the sidelines and has something or other in his possessions that I can't remember now, if anything... he should've been the one to surprise kill the monster. Not Kate. Just showing up during the Jack/Smokey fight and shooting him because that would follow established lore and be a very cool surprise. Not Kate for no reason with that stupid line of hers and....
Haaaaaaa....
