New Warehouse 13 theory: MacPherson has been trolling everyone the whole time.
1. He debronzed HG, thus giving her the chance to completely destroy the world. (She ultimately didn't, but he had no way of knowing she'd end up redeeming herself eventually.)
2. He and Artie collected Collodi's bracelet from Walter Sykes, and there's a decent chunk of time in which MacPherson was running around without the Warehouse's knowledge. Putting a word in with Sykes as to just where he could take out his anger is both feasible and perfectly in character, considering how he 'helped' Claudia hack into the Warehouse.
3. He had to know what the watch would lead to; I've wondered before now what it says that he didn't try to find and use the astrolabe himself. (Probably because the Phoenix did the job just fine, but I digress.) Sure, he could have left it for Artie in the hope that Artie would be noble enough not to track down and use the astrolabe... ooooooooor he could have been playing an even longer game than Mrs. Frederic gave him credit for. Make it so that Artie is desperate enough to find and use the astrolabe (either because of HG's little Ice Age or Sykes blowing the Warehouse to smithereens), and BOOM, instant Dark Side. After all, if the Phoenix didn't get Artie there, There Are Ways.
4. While I doubt the show will actually go there, James MacPherson is undoubtedly enough of a bastard to have set something like this in motion. THIS IS MY THEORY AND I'M STICKING TO IT.
