No Hiro or Peter this episode? Dissapointing.
That was the best part of the episode! As much as I usually like Hiro for his comedic relief, this Hiro in feudal Japan storyline is extremely boring!
Monica is a good new character. For once I'm not really annoyed with a new addition. It'll be fun to see her watching tv to absorb information for the eventual upcoming finale. What will she watch? Karate movies? Let's place our bets!

I love how Claire is the only character who's been in every single episode. She really makes the show for me. As much as how cheesy the whole Claire and West love thing is, I actually enjoy seeing them together now. He doesn't make me cringe anymore. It's sad though that Claire will end up causing Noah's death as a result of this friendship. I wonder whether it'll be an accident or if West truly has an evil side we're not aware of.
What is up with the cockroaches?
I think we discussed this last season. They're just symbolism for Sylar. Remember how Mohinder once gave a lecture on cockcroaches and how hard it is to kill them, that even if you cut off their head they'll still be able to survive for days? Well, it's pretty fitting for Sylar.
