One was seeing that Daphne has damaged legs and is forced to use crutches when she has no powers. Which means that all the time we've seen her move around normally, she was still using her superspeed in order to walk, which I though was pretty neat twist.
Another moment which was pure geeky was when Hiro and Ando show up in another comic shop and have the two comic book guys (one of them Seth Green) see them on the cover of the Nth Wonders just as one of them is about to buy a 9th Wonders issue. So of course you know that next week there's going to be the comic book guys helping out their comic book heroes.
And we get both Peter and Nathan have the start of a real conversation regarding how they see the other--Nathan feels he's always has to be the one to help Peter because he feels he can't take care of himself, while Peter believes Nathan can be so much more than just somebody's puppet. Shows both the love and frustration they have for each other as brothers quite well.
And of course, we get "father-daughter" moment between Claire and HRG in which the later finally teaches her how to fight, or at least swing a piece of wood, and how she is always angry that her adoptive father always leaves. HRG hard-knocks character has been sorely lacking this season and at least it's somewhat brought back in this episode.
Of course, there were way too many moments that I thought were very groan worthy. I don't know about some, but the whole Sylar and Elle pairing being essentially a super-powered "Bonnie and Cylde" seemed a bit much, what with Elle clearly manipulating Sylar into "doing whatever he wanted" without having to listen to anybody just another example of how the show's once badass villian is being made into a patsy. Whatever happened to the Sylar who could manipulate others from the past two seasons? Then there's Hiro with the ten-year old mind teaching Matt about being a hero by throwing corn at him. Why are all of the sudden Matt and Hiro listening to him since he literally has the mind of child now? At least MohinDUH! has stopped turning into Brundlefly (and I bet the ladies were squelling when they saw him pop out of his web cocoon all naked) but what did he really ad to the episode? Oh, he tells us that the powers are being affected by the eclipse, which anybody watching the show could already figure out, but does he explain why? Of course not. And this guy's supposed to be a brilliant scientist? Uh huh.
