"Heroes" had presented a flashback episode through "Villains" that aired on Monday, November 10, and the next episode will see Hiro ready to face a battle against Flint and Knox. The hero that can travel through time will be aided by Ando, Claire and Peter during the fight.
Titled "It's Coming", the episode chronicles the group of superheroes' anxiety of an unknown happening that will come along with the approaching moon eclipse. It is known that they got their superpowers when the first eclipse occurred and thus, they have no idea what the second one will bring. Meanwhile, Nathan learns of his father's plans, Matt tries to revive Angela and Sylar meets with Elle.
Mohinder begins testing of his newest superpower formula, and finds out that he needs a catalyst. Arthur comes to realize that the catalyst is not "something" but rather "someone", which happens to be Claire.
"It's Coming" will be aired on November 17. Two previews of the episode have been outed, the first one is the one played at the end of its NBC broadcast while the other one is the promo played on Canadian's Global channel.
