The CW has released some official preview images to promote the May 23 season finale of The Flash.
The season finale is called “Finish Line” and here’s a very short, very vague description:
SEASON FINALE — With nothing left to lose, Barry (Grant Gustin) takes on Savitar in an epic conclusion to season three. David McWhirter directed the episode written by Aaron Helbing & Todd Helbing (#323). Original airdate 5/23/2017.
The new photos can be found below; ideally there are some new spoilers within that gallery, at least. And, hey, this may be the “Finish Line” for Season 3 but The Flash will be back for a fourth season in the Fall.
