[ Rezo startles a little at the grab, nearly missing the rather important information Zelgadis is trying to tell him due to being distracted both by the gesture and the fact it isn't being followed up by a punch to the jaw. But when he does register what Zelgadis says he doesn't even bother trying to hide his frown. He immediately wants to probe for more detail but Zelgadis is already trying to move on. ]

Zelgadis...

[ Discontent, Rezo follows along and supervises the magic process for the next patient. The magic flows more or less as it should and the words of the incantation are spoken true, but with obvious difficulty. When the spell ends, the heavy sound of Zelgadis's breath is echoing in Rezo's ears, and then-

Rezo tilts his head. ]

What?

[ He catches the whiff of fresh blood a moment after Zelgadis clarifies, and he reaches into his cloak to rummage for something useful. ]

Oh. Lean forward. And- here.

[ He holds out a handkerchief (his cloak can store a surprising amount of things) so Zel hopefully will not have to wipe the blood off onto his sleeve, oblivious to the fact it's too late. ]

You'd better explain what's going on. Right now, it appears as if your magic is draining much faster than it should.
