Well all the PCs were basically kidnapped, and time doesn't seem to ever pass in the prison, but it does. So we will be returning to Earth, and as kidnapped kids/young adults/whatevers, we're probs going to want to reach out to our fam asap. We'll discover exactly how much time has passed, and also we'll pretty quickly discover how unsafe we are. So yeah, you can have NPC family, those members may even be as yet untapped Streamers, and we could even bring those NPCs into the in character roleplay instead of just having them in the background, but how much of a role they'll play will be determined by how the characters react to them/how long you're willing to write for them.

tl;dr you can have npc fam but whether its background, a cameo, or a second character is up to you and the group- like if they don't come into their powers or they'd otherwise just be safer without the team around, may be better to leave them, but if you just want two bro chars and we recruit one later in the rp and they come into their powers then, thats fine :P

And yeeeeeeeee TP was p good, the not being able to kill thing was weird though, and the villains were boring, so this is my own somewhat more zany take on the idea!
