Psychic cops, flying Stop signs and convertible pants

Spoilers for "Heroes," "The Class" and "How I Met Your Mother" (in that order) coming up just as soon as I decide what the comic book about my own life would be called...

So many questions, so few answers in episode two of our superheroic journey. We realize that Hiro traveled through space and time for his jaunt to New York and got to witness both the apocalypse and the results of the election. Are they related? Will Hiro's return to the present prevent both things from happening? We're two episodes in, and I still have zero idea what Niki the stripper's powers are. Her mirror image can not only kick ass, but alter reality? Hmm... And can Peter really fly, or is his power to tap into the powers of people around him? Was the evil conspiracy trying to make some kind of symbolic point by having their hitman pose as a cockroach exterminator after Mohinder's cockroach talk last week? At what point will NBC have a "Heroes" / "Friday Night Lights" crossover where Claire gets run over by one of Kyle Chandler's players? And how much are the writers enjoying the quest to creatively maim her?

I know many of my fellow geeks were psyched for Greg Grunberg's appearance, but he wasn't exactly playing to comic relief type. Still more questions: Is our brain-stealing serial killer tied in to the nuclear detonation or will there be multiple big bads this year? Is Clea DuVall allowed to make a TV appearance on a show that doesn't involve supernatural powers?

And a question for you folks: in the original version of the pilot, Isaac cut his hand (or possibly hands) off to prevent himself from making any more clairvoyant paintings. I don't remember that scene from the final version when I watched it weeks ago, and he obviously wasn't an amputee in this episode, so was it cut or did they just ignore it?

Decent episode three of "The Class." Holly's queeny husband is completely absent, and her getting gobsmacked by the Stop sign was the single funniest thing in all three episodes. But I can't help feeling like the show would be much better if they trimmed the cast down to Jason Ritter, Jesse Tyler Ferguson, Jon Bernthal and one or both of the twin sisters (I go back and forth on how much Heather Goldenhersh's speaking voice annoys me). Maybe I'll feel differently when they do more mixing and matching among the eight, but there's too much dead weight.

And so, "HIMYM" finds a way to telegraph the end of Ted and Robin's relationship by presenting his parents as an exact parallel. Again, I'm cool with them staying together for multiple seasons, so long as the show doesn't drown in pathos when it's time for the inevitable split. The Marshall and Lily portion of the narrative triptych was my favorite, but there were pleasures to be found in all three. Barney got some karmic payback for last week's multiple "rack-jacking" of Marshall by having Steven Keaton do the same thing to him.

What did everybody else think?
