Arthur bugs me. Every time the heroes got close to stopping him, he'd just pop over with his time/space warping power that he got from Peter who got it from Hiro and just bitch-slap them down to kindergarden levels. I'm glad he's dead. I hope he stays dead. I was kinda hoping Peter would empty a few more rounds into his head, just on principle.

Oh, and I agree totally, the scene between Hiro and his mom was just beautiful. Those scenes, and the ones with Sylar, "Cake!" and "Huh, it does tingle." were pure gold.
