Cogito, ergo sum

Birthright, Asha didn't care one iota about her bloody birthright. She could feel the rage in her growing, her fists balled up tightly, finger nails digging into her skin. She hated being put on the spot, lessons with Lana were so much less stressful. Then as if one Morrigan was bad enough there were duplicates. The only thing keeping her from running away crying was the rage that was far stronger than the urge to cry.

Finally the rage built up to the point that she lost control of her magic, a sudden burst of energy and books spilled off the shelves of the bookcase.

That's a really low blow bringing up dad and it's really hard to do magic when you're looking down at me, judging me. Perhaps the problem isn't me as a student but you as a shitty teacher. The anger was still oozing out of her, she was so angry that when she tried to do the duplicates again, she succeeded.
