Seems like the folks at The Flash decided this was the day to make news. After already having photos of Reverse Flash leaked and the news the Victor Garber will play Dr. Martin Stein (one-half of Firestorm)… now we get word that the role of Hartley Rathaway / Pied Piper has gone to Smash alum Andy Mientus.
Hartley is a genius who used to work at S.T.A.R. Labs until a falling out with his mentor, Harrison Wells (Tom Cavanagh). The particle accelerator robbed Hartley of his hearing, but inspired him to create a series of sonic weapons that he uses in an effort to punish Wells by destroying his new protege: The Flash.
Piper is one of the few openly gay characters in the DC Universe and the television series will not be shying away from that part of the character.
Mientus is scheduled to be in the 11th and 12th episodes of the season.
