Xan:
Renata if you could NPC, Xan for a bit. I am going for a hospital stay and don't know all the details.
Renata, I think the simplest way to handle this is when you post, say what Xan is doing too, and roll for her if needed.
Xan's player is in a couple of my other games, so we're "writing around" her health there, too.
All RPGs sometimes have a player be absent for a session or two-- we can do this.
