Smallville Season Five: Splinter

This may be my favorite episode of Smallville ever. Just... wow. I loved seeing into Clark's fears, seeing how they progressed from panic to hysteria to near-madness. Tom Welling continues to absolutely knock my socks off (in the commentary James Marsters talks about how impressive he finds Tom, as an actor, and I am definitely agreeing). I mean, wow.
