"That is a huge question motivating the next few episodes," says executive producer Roberto Aguirre-Sacasa. "I’m not even kidding you! It’s a giant question. It’s funny: KJ (Apa) called me and was like, 'Dude, do I really have to dye my hair back and forth, back and forth?' I was like, 'KJ, I don’t know what to tell you, dude. We’ve gotta figure out a way to do it.' (Laughs) He was a real trouper about it.
