Elsewhere, we finally meet Mrs. Nathan Petrelli, played by Rena Sofer (who is also sister-in-law to Jack Bauer in 24). The whole Petrelli clan sits down to a fake brunch with a journalist, during which Nathan's tryst with ikiN is almost revealed, but Peter - not invited to brunch initially, and fairly bitter about it - covers for Nathan. Although it's pretty clear Rena doesn't believe the story. Later, Nathan admits to what happened with him in the desert, and that he flew away, and Peter wants him to get the missing Isaac painting back from Linderman, which Nathan says he can't do, but we hear him on the phone and it sounds like Linderman gives it up. Confused? Me too.
Simone's father dies. Isaac is AWOL. D.L. has kidnapped Micah from Niki. Micah is not happy and thinks his dad is a villain, until D.L. saves a girl from a burning car by morphing through the glass - with an assist by the suddenly appearing Hiro, who freezes time to help.
Then Micah amazingly games a non-working pay phone, which means he has powers too. He calls his mom; ikiN picks up; Micah is completely onto her and asks to speak to his mom; D.L. busts Micah during this call. Oh, and ikiN has a name: Jessica.

There!!! You forgot that minor detail!!!!!
When Future Hiro met him in the subway carriage he said "You look different without the scar". I'm assuming that Hiro has never seen Peter without the scar - until he travelled back in time. Hiro and Ando are on now their way to NYC. Before they get there to meet Peter, he's going to suffer an accident, and get that scar.
