A bit confusing (at least for me) but very good.
First of all, lol, future Peter is hella hot and he looks so buff, loved his arms and his badass mentality now that he got control of all his powers, he totally rocked this episode. His showdown with Sylar at the end i got goosebumps during that sequence it was so hot.
Sylar is hot but he was an ass tonight. Claire is my favorite superhero and he kills her, i almost cried.
I Kinda knew something was off about Nathan when he entertained the elimination idea.
Niki finally gets Jessica under control, but Mika 
Matt? what the hell happened to you?
So if Sylar didn't die who exploded? Nathan?
I don't like Niki and Peter together, it seems wrong, a mismatch. Bring back DL he is hot and a better fit.
When Ando and Hiro got reunited it seemed a little gay but i liked it. True friendship rocks.
The closing sequence was awsome.
"A boy sucked all the oxygen out of the air and everyone suffocated" wow what a "power"
Claire's boyfriend was kinda cute
What that boys power at the start of the episode? Did anyone get it?
Curious about Molly.
I know i am missing some stuff, but ill come back when i watch it again later this week.
