We were at the Comic-Con panel. Here is the breakdown:

1. Nathan is a Jesus freak now. He believes all powered people are angels (leading me to think that he should dress up in an angel getup and fly around). Linderman is his god.
2. Mohinder has formulated a way to give people powers. In the future, this has gotten out and now everyone has powers, including Not-So-Unspecial Ando, and that makes the world explode. Ando pwned Hiro with a majikal red bolt GENERATED IN HIS HANDS.
3. Mohinder (AKA Father of the Year - please remember that this takes place immediately after Powerless) has sent Molly on a plane, alone, to whereabouts unknown, without telling Matt, and also was going to leave for India. Matt, btw, is stuck in a desert with a scorpion on his face. Future!Peter teleported him there.
4. Future!Peter was the shooter, Future!Claire is badass and kind of an uncle-****er. ("I always loved you" = just what it sounds like.)
5. Sylar does NOT eat brains. Best line of the show: "Eat your brain? Claire, that's disgusting." TAKE THAT.
6. Present!Peter is stuck in the body of a thug imprisoned in Level 5. Future!Peter put him there. Present!Peter is currently played by Weevil.
7. Mohinder knows kung-fu. (Srsly, his power appears to be... kung-fu.)
8. As much as it pains me to say it, the scenes between Sylar and Claire came off as a bit... heterosexual on both sides. Sylaire... let me unsee it.
9. The end-of-episode Momologue is a Yeats poem.
10. Hiro has inherited his father's company. Kaito gave him a video message instructing him not to open a safe, which he promptly opened, and then the contents of the safe were immediately stolen by Daphne, who is spunky and kind of cool.
11. In a strange role reversal, Maya is vaguely squicked when Mohinder strokes her arms in a fit of scientific glee.
12. Our favorite characters for this episode were: Peter, Hiro, Maya, and Claire. That ****'s ****ed up.
13. This episode really sucked. OMGWTFPOLARBEAR, dude.

how does it appear heterosexual like on both parts..?

We were making gagging sounds. Here is roughly how it went:

NOTE: Before this scene, Sylar waxed poetic about love. Trufax! "How much of the brain do we use? Ten, twenty percent? Imagine what we could do with the full hundred. Learn how many angels dance on the head of a pin... why there's evil in the world... how to make love stay..."

He also had his lips very close to her forehead when he was uttering his totally awesome brains line.

Now, the scene:

[Sylar starts to walk out the door, leaving a freshly-healed Claire on the table]
CLAIRE: Wait! Why didn't you kill me?
SYLAR: Oh, you poor girl. You barely know anything about yourself. You're different, Claire. Your brain isn't like the others'. You're special. I couldn't kill you, even if I tried. You can't die. And now, I guess... neither can I.

Okay, that last part was cool. Even if Sylar being invincible is weird and Sylaire is EVEN WEIRDER. Plus, it doesn't make any sense that she can't die - she did once, in the timeline that came before 5YG.

I think the heterosexual remark comes from the fact that Zach is rumored to be gay. Either that or it's due to the fact that he has a lot of homoerotic undertones in his scenes with men. There are a lot of Sylar slash ships and I know some people are/were hoping Sylar is gay. I think the 'heterosexual' comment means that there is some sexual chem between the two of them.

Which means, of course, that he will soon be her uncle.

that's already rumored anywho..I think Zach and Hayden have good chemistry in real life and it prolly translated onto screen
