The Pied Piper is returning to The Flash.
Andy Mientus will reprise his role as Hartley Rathaway, aka Pied Piper, in an upcoming episode of The Flash, reports EW.com.
He will appear in episode 17 titled “Flash Back,” where Piped Piper returns “to wreak havoc once again on his former colleagues when The Flash impossibly revisits an earlier timeline.”
Mientus made his debut as Rathaway last season as Harrison Wells’ protege-turned-metahuman after he lost his hearing during the Particle Accelerator explosion.
The Flash airs Tuesdays at 8/7c on The CW.
