The boy is certainly in desperate need of medical attention, Jon is certainly right about that. However that "we" remains a load-bearing we at the moment, as Murmur remains utterly impassive as he watches the goings on with a level of disconnect Jon has rarely been privy to. This one was not of their flock, not yet, and therefore firmly out of his purview.

Thus, if Jon expected motivation on the angel's part, it was going to take more than implied requests. He didn't want to get involved in this, after all. To him it wasn't any of his business, but Jon was upset and he could tell Jon was going to only grow more upset if Murmur didn't give him a nudge on the necessary course of action.

He can't get involved on his own, but he can get roped in.

He remained, perhaps frustratingly, calm about the whole ordeal.
