Uhm, probably too late for this, but why are you healing the stun damage? A simple stim patch can help with that, at least for a while. But at 8-9 boxes of P damage, that means even with the smallest accident, he's dead and we're screwed.
Going to wait for a moment, at least for Still Waters to do something. Assensing would help I guess; and he's still got the lie detection spell on him, wondering what that shows.
