Okay. It was just I never figured the angels being okay with Gabriel (one of their stronger angels) just up and leaving. I still think it makes sense to have someone watching him, mostly to keep tabs on the group's activities. Plus, angels are jerks so 'kill everyone if you tell them their orders and they refuse to follow along' would be a valid order. I mean, when you have general out with the troops, you'd wanna know what's going on and have someone dependable dispense orders to the 'lower ranks' and if they disagreed, just wash your hands of them.
