It would figure, wouldn't it? The one curse she could stand, the one time it did something mildly useful... it couldn't last. And it had been different for everyone; what if it had ended differently for her?
So it'd been a haunting nightmare. Something to put her on edge so that, finally, when she'd seen just how the curse affected so many? That some had even died? A little frustration, a simply punch aside to the wall...
Had gone wrong.
It seems the more frustrated she gets, the more the fire simply doesn't want to cease. She'd very nearly set off one of the fire alarms in her little room, and she wasn't sure if there were others yet... She sighs, clenching and unclenching her hands. No outburst for six minutes now. Maybe--
Voice then, startling enough that it hits her nerves and makes her loose her concentration and she knows that voice.
"I thought I sa-- you--!"
Stops herself at a familiar flicker of heat and crackle and yellow sparks around her hands and it's all she can do not to erupt into a rather explicit line of curses.
"...don't." Tries to make her voice all command, but it wavers around the whimper of concentration that gets broken anyway. Flame crawls up her arms a moment, singes a curtain, and she jerks away from it with a soft sound.
