Still loving Bill Paxton. I was a bit concerned that they were going to make him The Clairvoyant, but they seem to be going in a different direction. Or possibly not...Deathlok's thermal imager only targeted Coulson (watch it again, you'll see what I mean). Also, that speech about, "I must be getting old" just seemed weird. I feel there's a hidden meaning in there and we're gonna find out some nasty stuff about Garrett. After all, who put the idea of straight up killing The Clairvoyant in Ward's head? Triplett. Who works for/with Garrett.
Ward seemed a little off, but I think it's due more to character evolution than mental tampering, etc. The writers are pushing the "he loves Skye" thing WAY too much for my liking, though.
As for May, she's clearly not evil. She's reporting to someone and has higher clearance and she's incapable of breaking her oaths, so she seems devious.
Although he doesn't seem to be credited anywhere, how about a little round of applause for Brad Dourif. He gave another chilling performance without speaking a single line.
