As the threat from Agent Liberty continues to mount, the newest episode of Supergirl, titled “Bunker Hill,” looks to be swapping out some brawn for some brains thanks to the help of Brainy.
New to the cast for the fourth season is Sam Witwer as Agent Liberty, Rhona Mitra as Mercy Graves, and Bruce Boxleitner as Vice President Baker.
Meanwhile, Nina reveals to Supergirl her ability to “dream the future.”
New episodes of Supergirl premiere Sunday at 8/7c on The CW.
