[Movie] LOST

If Patchy/Mikhail knew who they were and was going to end up fighting them, why the hell did he not shoot to kill? He purposely wounds Sayid then stitches him back up, then lets Locke roam around at will and sits down to talk to Sayid and Kate without any kind of back-up weapon nearby? Seriously, wtf? To add to that, Klugh doesn't attack Kate with a gun or weapon of any kind? Locke playing chess while a suspected Other is lying on the floor tied up in the next room? Why is nearly everything in this paragraph a question that will most probably never be answered?

The promo on ABC's page shows

Spoiler:

Mikhail revealing that the Others have no need for Sayid or Kate, and possibly no more need for Locke. So why in the blue fuck would he even contemplate keeping them alive? Why not just shoot them both and drag Locke away?

Why would the failsafe for a "Hostile invasion" require you to sit and beat a game of chess? Oh yeah, that's right 'cos when those Hostiles come running out the jungle you can tell 'em to chill for a sec while you beat the comp at chess. Or when those hostiles have taken over and have you bound or gagged, you can shuffle over to the comp, beat a game of chess, and go through an annoying "press 1 if you are lying in pain.." system to get the place to explode.

Jam it back in, in the dark.
