But even amid a family of mediums and superstrong warriors, Number Five (Aidan Gallagher) stands out.

This has separated him from his siblings in multiple ways.

That made the character particularly difficult to cast, according toshowrunner Steve Blackman.

I just instantly knew, that’s Five.

Aidan was such a professional on set.

He just brought that brooding anger and gruffness that had to be Five.

But while his siblings are focused on that, Five only cares about stopping the impending apocalypse.

“Five has sort of had his own little life aside from everyone.

That was one of the most interesting things about Five that I got to play.

He definitely has a different relationship with the pacing of the series than the others do.

“If I were to do a scene with her, I would make dialogue for her.

So Five is playing the part of Dolores.

That is a fun dynamic that I was definitely looking forward to shooting.”

“He said, ‘You got it, man.

Great job,'” Gallagher recalls.

That was when it happened.

He pulled me aside and we talked for a moment.”
