Did Locke play the players? Or did he just choose sides? Think about it:

He tells Jack that the meds should get locked in with Guns & Drugs...who's got the Meds? Sawyer! Jack confronts Sawyer, who's a "I get mad AND even", type of guy.

Jack comes to the hatch and Sawyer's sitting around popping his newfound meds he's just gotten back, while Locke is running around hiding guns.

here's the rub...Sawyer cant track worth a damn, but somehow finds Locke's hideout...meanwhile Locke is a great tracker and could easily trace the guns' movement to where Sawyer took them...

Either he's put one over on them all, including Sawyer, or he just made a pact with him. But if he did, it means he had a hand in the harming of Sun as well, and dont know how I feel about that.
