I'd keep dialogue moving from left to right in each panel. That first panel is off putting by having the silence as an answer appear before you question. Simply flipping the characters would have solved this problem. It also wasn't fuinny, so you should work on that as well.
I'm guessing your silence in panel 3 is probably supposed to be another reaction, but it works better as an awkward gap before the girl's question. Or maybe that was the intent. At any rate, I haven't watched minute one of that Heroes show, so.. "I got this one".
You lied. that did not rock. at least my comics are decent. that sucked monkey balls and was awful. like waffle without the w. i did get the joke though. just make a more subtle joke and more funny.
