Because once again, they were wonderful. I love that Ando, for all that he thinks that Hiro is a little OTT and pompous, backs him up when he needs it. They are adorable.
Niki is more interesting when she's interacting with DL and not!Niki.
Cheerleader's Dad when he hears the message has a fantastic reaction. See also the whole bit with the Cheerleader's putative bio-parents, who I presume aren't.
I do wish that Mohinder's turns out to be evil girlfriend would leave Issac alone. He's messed up enough as it is. He is still probably the most intriguing character on the show, and after seeing the trailer, I'm intrigued to know if he does need the drugs to see things. I mean, I assume that they'll go the normal route of him not needing it, but I live in the hope that they'll be brave and actually have him need it, if only if it would be an interesting twist.
Since he's the first kid we've seen with two "mutant" parents, does that make Micah Nate Grey/Cable?
More amusingly, the 'Heroes Unmasked' programme after was mostly about Issac, and Santiago Cabrera is just the most adorable thing ever. I don't know if it was deliberate or not but you had him sticking up for Issac when everyone else was pointing out his bad points. And then you had him and Milo Ventimiglia intercut talking about whether or not Peter stole Simone from him.
It was sweet and adorable.
