He defeats the rest of Team Flash, all of whom attempt to stop him.

I thought you did a good job of tracking Barry gradually losing his emotion in this episode.

How did you approach playing an emotionless Barry?

GRANT GUSTIN:I was nervous, actually, about it.

It was supposed to be toward the end of last season.

I was nervous about starting it because it was a lot of work.

[Showrunner Eric Wallace] had referred to it as Spock Flash, just completely emotionless.

So, it was definitely a fun challenge.

Like you said, I tried to build less and less emotion as the episode went.

We were trying to find those checkpoints of, “Okay, here he stops using contractions.”

There was this progression to the dialogue.

It was fun, definitely different than any other challenge I’ve had on the show.

Did you actually approach it like you were playing a completely different character?

Yeah, kind of.

As it built for sure.

In that first scene, there was that fun excitement.

That was still Barry like, “Holy crap, I have speed thinking now!”

How does Barry handle the emotional fallout from his fight with the team and hurting Iris?

Yeah, it’s obviously really hard on Barry.

There’s an immediate emotional fallout.

We pick directly up with this moment in 703, with a very emotional scene.

He was unaware of what he was doing.

His mind had been taken over.

So, it weighs pretty heavily on Barry.

Thankfully, no one turns on him.

What can we expect from this version of Harrison?

Well, there’s kind of a twist there, too, like always when it comes to Wells.

It’s not like necessarily the real Harrison Wells, I guess.

It’s been nice.

It’s definitely the next stage in their relationship.

The Flashairs Tuesdays at 8 p.m. on The CW.
