We pick up right where part one left off.
In the meantime, Caspar will wipe Past Noahs memory to protect the twins.
(ASIDE: If Ive figured this out, Caspars power involves storing peoples memories inside those pennies?
Erica tells him not too worry and thanks him for his service.
Hachiro realizes something fishy is going on when hes locked out ofEvernow.
So, he creates Katana Girl as a back door into the game to give Hiro his own hero.
While the world is reeling from the terrorist attack, Carlos, a.k.a.
Gutierrez, is being questioned by a commanding officer about his role in the firefight with the Taliban.
(So, this is why Carlos felt so ashamed in the premiere.)
Farah decides to leave the military and to rejoin the company she used to work for.
You know, The Company.
After thanking her for putting a smile back on his face, Hachiro hands himself over to Harris.
NEXT: Save the boy, save the world
Future Hiro and Present Angela time travel back to 1998.
Unfortunately, they arrive in Odessa instead of at Angelas castle in Geneva (#FirstWorldProblems).
Hiro tries using his powers but cant because Baby Nathan has taken them.
Angela decides that its best the twins be kept apart so Nathan doesnt steal Malinas powers.
Noah asks Nathan for a ride back to the future, but Harris shows up and attacks the home.
In a nice bit of familial teamwork, Nathan and Noah take out the Harris clone.
Angela promises shell ensure Malina finds Nathan in a years time.
Shortly after Nathan and Noah leave, Farah pays Angela a visit.
Malina will probably die saving the world.)
In a surprising move, Erica rewards Quentin for saving her life by letting him see his sister.
Then, Nathan sends him back to the present.
Unfortunately, more Harris clones show up at the home.
Noah arrives back in Midian, Colo., to find Quentin still alive.
After bringing Quentin up to speed, Noah conveniently walks off in search of his gun.
Yes, Quentin is a traitor.
Has he been one since the beginning?
I cant remember how time travel worked inHeroes, and the show doesnt explain the rules here either.
However, it seems as though not much in the present has changed.
Did Noahs trip to the past always happen and thats how we ended up with the present?
Well just have to wait until next week.
