Patrick J. Adams is suiting up again.
This time as a mysterious hero on DC's Legends of Tomorrow.
He'll join the finale, which is titled "Legendary," apparently a leaping off point for this beloved character from DC canon, who will then recur during season 2.
TVLine formerly reported on a mysterious hero coming to the show as having a "mysterious past and an equally mysterious agenda."
I'm pretty sure we can rule this one all around mysterious.
One thing we do know? He is not Booster Gold, so keep on guessing!
That's just fine with us, as the idea of Adams in a superhero suit instead of his traditional Suits style of button down and tie has us kind of giddy.
Tonight we're in for the second half of the 1950's adventure.
On DC's Legends of Tomorrow Season 1 Episode 9, "Left Behind," Kendra, Ray and Sara decide to move on with their lives when they realize they are truly left alone.
While Kendra and Ray will grow closer to each other, Sara will rejoin the League of Assassins.
Check out photos from the installment below, and the sizzle reel for what lies ahead on Season 1 (hint: Jonah Hex, but no mysterious Patrick J. Adams!).
