The Flashis doing the time warp again.

“Bart is distracted by his, you could say, love life a little bit.

At the end of the day, they’re just trying to save the world as usual.”

ENTERTAINMENT WEEKLY: How would you describe this episode?

The whole episode revolves around our ridiculousness.

We felt very, very special when we were filming this episode, more than we have before.

We always feel special, obviously, but this one is just an extra-cool one.

I just think it’s really sweet.

It shows the dynamic of the siblings in another way.

I guess you could use the word “respect” that Bart has for Nora’s ideas.

If she has an idea, he has the better idea.

I appreciate your idea, but I like mine better."

So that can work sometimes or get them into trouble sometimes.

This version of Nora obviously isn’tthe one from season 5.

Do you approach her as a different character when you’re performing?

Yeah, I do.

Whereas this Nora, I think she’s a little bit more grounded.

When I film sometimes, I’m like, “It’s not fair!

I miss the other Nora and being the goofy one that messes up and gets into trouble.”

Now it’s kind of Jordan’s character who gets to be that one.

I’m sort of the more older, naggy, responsible sister.

The last time we saw Nora and Bart was at their parents' vow renewal.

Living together and working out their power dynamic, really.

They’re both adults in their own world.

Bart is distracted by his, you could say, love life a little bit.

There’s definitely a love connection that happens in this episode, which distracts him and kind of funny.

At the end of the day, they’re just trying to save the world, as usual.

How do they react to returning to this early point in time in their family’s history?

I think for Nora, the stakes are always a lot higher because she’s older and more responsible.

Whereas Bart sort of has this more enthusiastic, “I want to see this!

I want to see that!

Oh my God, look at that!”

He’s very much a little puppy.

Bart is more like, “Don’t worry about it.

Let’s just have a great time.

No matter what happens, we’ll figure it out.”

That’s kind of like his attitude, which I don’t relate to personally.

[Laughs] I’m much more of this version of Nora: prepared, looking five steps ahead.

It’s interesting to see them meet their mom’s ex-fiance, Eddie Thawne.

He’s just a kind, gentle, lovely, lovely person.

I think, again, Nora is just really focused.

So you’ve seen the episode?

What was your reaction to watching it after shooting it months ago?

Just stuff like that is really fun.

Did working with Jordan empower you to improvise in moments when it made sense for Nora?

It depends on the character.

He gets really authentic reactions out of me.

When you watched it, did anything play differently than how you’d imagined it?

No, we had a pretty clear vision of what it was going to be like.

Is this the last time we’ll see Nora this season?
