Fringe, "Of Human Action": Drive, he said

Speaking of shows that it sometimes takes me days to get to, I only got to watch the latest "Fringe" this morning, and I'm not going to have time to really write about it for a couple of days. So in the interest of letting those who care talk about it, I'll just say that I thought it was a solid episode with some good (but not sledgehammer-y) parallels to Walter and Peter's situation.

What did everybody else think?
