Broadway star Andrew Mientus guest stars as Pied Piper Hartley Rathaway.

The Pied Piper doesn't look all that menacing, even arms up in the air...

So the Pied Piper can manipulate sound waves. That would be cool.

He's feeling mighty big, walking on cars like he's doing here.

The Flash has the Pied Piper down, but wanna guess it's not for long?

The Flash has excellent posture, as noted here, shoulders back.

Do you have a persistent ringing in your ears? It could be signs of tinnitus.

Things get physical between The Flash and the Pied Piper.

When your ears hurt, there's little you can to but writhe in pain, as shown here with our model, The Flash.

Immediately, it becomes apparent there will be no winner as one by one The Flash and Pied Piper are up and down up and down.

And The Flash is back down on the ground again. It's like dueling jacks in the box!

Yes, we really do get it that they aren't popping up and down. It's just fun to chat about the photos that way. Weeee!

This is a nice shot of Hartley. He's not a bad looking bad guy.

The Flash poses in front of Rathaway Industries, which must have some connection to Hartley Rathaway.

Hartley is reaching for the stars. Or grabbing for the moon.

The Flash is apparently hunting for Hartley Rathaway.

The Flash could have chosen a warmer greeting. A choke hold isn't it.

Barry and Joe discuss things coworkers and roommates and fathers and sons discuss.

Barry is definitely enjoying the discussion, whatever it may be about.

One can only assume Eddie was in a rush to get to work because that is a definite hair don't.

Considering the gravity of having a Pied Piper rolling through town, there are a lot of smiles coming our way.

Iris finally gets the job of her dreams as a cub reporter for the Central City Picture News.

Harrison Wells holds court at a press conference, perhaps about the Pied Piper?

Harrison looks perfectly at ease answering reporters questions.
