Here's the thing about crazy powers, at least as they apply to Sam: while he'd had some difficulty earlier, that had been related to Sylar not actually being a demon, to seperating him from Jubilee's real body, to various outside forces that Sam had been forced to focus on at the same time.

With Sylar actually in his body, taking over all the physical responses and providing such incentives as attacking Jo and Dean, Sam is finding that, for once, something about these powers is pretty straight-forward.

Pushing, for instance, is always easier than pulling. Especially when it's all he has to focus on.
