We are ten minutes away from the twentieth episode of Flash season 3, I Know Who You Are. What we know going in is the Barry has returned from the future with data on the device that trapped Savitar in the Speed Force and the name of the scientist that built it. We also know that Killer Frost is on the loose and has teamed up with Savitar. Things are bad… m'kay.
Tonight's episode introduces us to Tracy Brand (Anne Dudek), the scientist who is more whack-job than genius at this point and we're told we will learn who Savitar is. And then we'll only have 3 episodes left to wrap it all up. Unlike Supergirl and Arrow, there have been no announcements about characters / actors returning for the season finale, maybe that will change after the reveal tonight.
I'm going to be live tweeting the episode here or you can follow along below.
