S01E23: 'How To Stop An Exploding Man'

Molly recognises Matt from a previous encounter, which diffuses the stand off between Mohinder and Bennet. After her illness relapses she tells the former policeman that a far worse threat than Sylar lurks out there, but if she tries to locate him then he can see her.

Hiro teleports to Ando’s rescue, saving him from a head slicing from Sylar before both disappear. They arrive in Japan, where Ando is left behind while his friend returns to complete his quest alone.

Niki, having left the wounded DL behind, encounters Candice and batters her in order to reunite with Micah. Crucially, she sees herself in the mirror not Jessica. They later leave the building as a family, bumping into Mohinder – who gives DL treatment.

Peter implores her to shoot, but his brother Nathan flies onto the scene, grabs him and sends them both soaring into the sky. Moments later, there’s a massive explosion in the night sky. It also emerges that Sylar’s body has disappeared, with a trail of blood leading to an open manhole cover.
