Also, for all the doctor talk, I'm pretty sure I technically was the doctor as jailer.
"You may protect a player from death twice, but also prevent them from being able to successfully perform any night actions on that same night." - from my role reveal.
Which I actually like a lot. I've done it in games past where I've hosted where I used a jailer instead a roleblocker or a doctor. It forces more strategy because if you want to save them, you also have to stop them from using their role. Or for mafia, if you want to roleblock them you also can't kill them at the same time.
