Extra filter against ALL from this world
Well, this wouldn't be an issue if that angel the idea hadn't been put in his head to start with. We just need to drag his arse to a contained space, and Death will put his soul back in him and protect him from the damage.
As this is so complicated, and delicate, I would greatly appreciate it if you could filter your entire post, not only from everyone from this world, but also from those closely linked to people from this world. Like, for example, the ones who live with Castiel or the vampire sleeping with the demon. We've had to be so careful about this for weeks now.
