Greetings once again faithful listeners. This week on Central City Underground, we discuss a thought provoking episode aptly titled "Therefore I Am". We finally witness the origin story of The Thinker and the Mechanic, and get one step closer to fully understanding their motives. Meanwhile, Barry is quite conflicted. His instincts tell him that Devoe is the bad guy they have been hunting, but Team Flash feels that Barry might be overthinking the whole situation. As if that wasn't enough to ponder upon, we see the return of another speedster fresh from battling starfish from outer space! Wally's back from Blue Valley just in time for any crises that may arise. Join us for another fun-filled discussion as we all wonder, "Where the heck was Dibny?".
