It looks like a familiar face is coming back to Central City – TV Line broke the news today that Andy Mientus will once again be playing the role of Hartley Rathaway a.k.a. the Pied Piper on The Flash in episode 17 titled “Flash Back”.
The title pretty much speaks for itself as Barry will be going back to to an earlier timeline where Piper is involved and that’s all that TV Line revealed about the episode.
Last time we saw Mientus on the show, he escaped after agreeing to help Cisco find out about what happened to Ronnie Raymond and Martin Stein on the night of particle accelerator explosion.
The Flash airs on Tuesday nights, 8/7c on The CW.
