The Flash Pied Piper Returns

The Flash: Andy Mientus' Pied Piper to Return for Alt Timeline Episode

The Flash‘s next time jump will bring back the meta that got away.

Andy Mientus will reprise his role as metahuman Hartley Rathaway, aka Pied Piper, in a trippy Season 2 installment, TVLine has learned.

Hartley — who escaped the Pipeline when Cisco let him out in Season 1’s “Crazy for You” — returns to wreak havoc on his former S.T.A.R. Labs colleagues in Episode 17, titled “Flash Back,” when the the titular speedster impossibly revisits an earlier timeline.

Speaking of crazy alt scenarios, The Flash journeys to Earth-Two tonight on The CW at 8/7c.
