So last session had a lot happen for my group, one character was written out, and another is sitting at double their wound threshold and out of it. On top of this, it all happened before the adventure's final space battle with the Empire.
My question is, how do I keep the players of these characters interested, until they either regain consciousness or the story reaches a point where their new character can come in? One of them says they're fine just watching the next session, I think they will be but I want to offer some options anyway, and I think the other player will want something to do. The thing is that so far I've only come up with offering them a chance to play an NPC for the session, is this a good option, or is there something I'm missing?
