Watch A Sneak Peek From The New Episode Of Supergirl Titled “Childish Things”

A brand new sneak peek from the upcoming all new episode of Supergirl has been unveiled. This new episode is titled “Childish Things” and it will air on CBS on January 18.

Kara and Hank (aka the Martian Manhunter) do a bit of training. Kara urges Hank to not hide who he truly is from the public and show everyone who he really is.

I am still in love with the fact that they introduced Martian Manhunter!
