If there's one thing Harry remembers about her past life, it's that it kinda sucked. Uncles, crazies and evil dark lords all out for her blood, mysterious mysteries popping out of the wood work (all but demandingto be solved) and, worse, school. Her life had been a dangerous adventure, the weight of the world pressing down on her shoulders.
She'd been almost relieved when it ended, surprised when it began again, and pleased to find she'd been birthed into a completely normal, non-magical world.
In that moment, she vowed to avoid adventure, forsake intrigue, live a perfectly safe (boring), peaceful (mundane) life, devoid of anything remotely dangerous (interesting).
You can imagine, then, her shock (and displeasure), at finding her adventure-free life so rudely interrupted by a slytherin-eyed boy intent on knocking her (and her fencing equipment) down in the middle of one of To-Oh University's many hallways.
(Though, to be honest, his smiling shadow had much more to do with her reaction than anything else.)
It was a hit and run, a gut reaction instilled by years of wizard-style guerrilla warfare and her innate sense that something wicked this way comes.
Her fist lashed out before her bag had even hit the ground, the dull thud of flesh meeting flesh- stark. The sound lingered in her ears long after she'd fled, ringing like the tolling of a bell.
Evil, and questions about its source, could damn well stay away.
