She could tell something was off by the way he was talking. Something in his mannerisms, but honestly Carol put it in the back of her mind until the bleeding was more under control. Yeah, it was definitely a mess. She crossed her arms, staring at him.
"Magic related? Don't remember you magic causing nose bleeds." She wasn't dumb. Putting two and two together was easy enough. "You shouldn't be performing magic if that virus is effecting you, John. You're going to bleed to death if you're not careful."
Sure, she was sounding just a little condescending. Call it the "mom voice". But Carol had a bad habit of looking after people she cared about (even if she was crap at assessing her won needs while doing it).
