At the Disco in his teens.

CARINA ADLY MACKENZIE:It was a really fun episode.

It really brought me back to the excitement and the fear of going out on your own.

It’s an exciting and scary time in your life and I really wanted to explore both sides.

We sat down with Nathan and I told him Liz was Max’s plan.

It’s world-altering for him.

He’s been completely helpless since he was seven.

The first thing was, the boys had to shave multiple times a day.

They were very mad at me.

It’s your body; I’m not going to make you shave it."

I think I can do it."

and “Do you want it off my stomach too?”

I’m getting a million texts and I’m like “Vlam, whatever you feel good about.”

It was very stressful.

Nathan had to do New York Comic Con with a fully shaven baby face.

Can we talk about Alex’s (Tyler Blackburn) goth look?

So he went full Panic!

At the Disco and My Chemical Romance.

At the Picture Show" because I was determined.

I was like, “No, he listens to Panic!

That’s who this guy is!”

So you didn’t have to add any youth-ifying effects in post?

How was the process of playing younger for the actors?

Nathan would drink an extra coffee and come in with a real pep in his step.

They all worked really hard to get this right.

It marked such a contrast to how they are now.

I think it’s that thing when you’re that age and you feel like you’re invincible.

We tried to center all these sci-fi instances around real human trauma and real human emotion.

So every instance we see Isobel and Rosa (Amber Midthunder) being friends, Isobel has blacked out?

Yes, all of Isobel and Rosa’s friendship was something she blacked out afterwards.

In the present day, Isobel doesn’t even remember knowing Rosa.

I don’t understand?"

She’s not being controlled, but it’s all part of what her body is hiding from her.

We have the who, where, what, and the how but we still don’t understand why?

Until I find out why it happened, I can’t prevent it from happening again.

There’s still questions lingering.

So, yeah, we’re digging into that in the second half of the story.

Are we going to see more teenage flashbacks to that night to fill in some of the blanks?

We will see more teenage flashbacks that will shed light on the moments that you missed.

The characters themselves still have questions.

Let’s talk about #Malex.

What’s coming up for them?

We go lots of episodes without them being in the same scene.

I think it’s a very grownup love story and I’m very proud of it.

They have both grown up in abusive homes in one way or another.

Then one of the happiest moments of his life gets smashed open by a monster.

The real monster in his life is his father.

Of course it gets to him, of course he feels it deeply.

It’s such an important story to me; it’s such an important part of the show.

I think fans should know that what you see in this episode is the beginning of them.

So do we see more of their past in flashbacks?

It wasn’t like that happened and they never saw each other again until 10 years later.

We’ve seen Max spiral when she rejected him before.

How will he overcome this?

This is the lowest point for them.

He’s a guy.

That’s where we’re going.
