There are, what, forty something people on the Flight 815 side of the island?
So far, we've only dealt with the core characters, the "cool kids" while everyone else just sort of...hangs out? I mean, what the hell IS everyone else doing all day while everyone else is dying/getting hurt/getting kidnapped/causing shennanigans?
These are the "Non-essential Islanders" we've actually had any contribution to the show as of this episode...
Arnzt - Dead.
Rose and Bernard - Played with rocks. Sorta' saved Claire from the Hatch door.
Scott & Steve - One of them is dead, the other one stands in the background every once in a while and looks cool. But he's helped people do stuff before.
Mr. "I've-got-every-disease-known-to-mankind-because-I'm-on-this-island-but-hey...Are-you-playing-golf? Can-I-Play?" Guy - Whined, then played golf.
Paolo and Nikki - Dead.
I think that's it. Them, added to the "cool kids" who are still alive, equals...Nineteen (counting Desmond). And three of them are dead, so it's actually sixteen. Sixteen out of 35?-40? people. I think there should be more involvement from the others, even if it's just like "Hey, Frank, have you seen Charlie?"
"I dunno, Hurley, maybe you should check that fat a** of yours, perhaps you sat on him."
Or maybe someone who has no connection to anyone can get killed by something for a change. "Hey, we found Jenny dead in the jungle."
"What?!"
"Yeah, I know, it's sucks, right? You'd think with all of these people dying we'd be kind of depressed and, y'know, more careful about stuff, but we just keep doing lots of stupid stuff without - hey, did you hear that? Sounded like something that could totally rip us limb from limb, let's go check it out!"
