Watch Hank Henshaw’s Big Reveal On Supergirl

SPOILERS for the “Human for a Day” episode of Supergirl follow.

Last night’s episode of Supergirl featured a dramatic revelation involving the history of Kara’s adoptive father, Jeremiah Danvers, and the true identity of D.E.O. agent Hank Henshaw.

While fans were expected Henshaw to eventually become his villainous self from the DC Comics universe, the Cyborg Superman, Supergirl threw a curveball by revealing that the real Henshaw died on the same mission as Jeremiah Danvers, and was replaced by J’onn J’onzz, the Martian Manhunter.

Check out the reveal in the below clip from the episode.

Supergirl airs Mondays at 9 p.m. ET on CBS.
