This week's episode was excellent. Spoilers ahoy:
Claire cutting off her toe, while predictable from the moment the biology teacher mentioned regenerating limbs and pinky toes being unnecessary, freeeeaaaaked me out. GAH, I squinted my poors eyes so hard I think I pulled a muscle in my face.
Also, I fully expected Takezo Kensei to either run off or die and Hiro to take his place and become the historical figure of legend, so as soon as Kensei was struck by those arrows my entire group of friends figured we had been right all along and were prepared for Hiro to have to dispose of the body. When he suddenly healed, however, we all freaked out a little. Marvelous. ;D
For the record, Peter Petrelli shirtless for an entire episode = priceless... almost as good-looking as Mohinder. Speaking of, it's my humble opinion that Sendhil Ramamurthy should be on every television show on the air, just so everyone has the pleasure of constantly looking at him.
