Hermione could not find anything on time travel, neither theoretical or documentation of experimentation. It was driving her mad, and she'd decided to take a break from her clearly useless search by taking a moment to browse the classics.
She hadn't expected anyone to be here, so she wasn't really paying attention when she rounded the stacks. She was busy looking at the titles and nearly collided with, wait, she knew him. Theodore Nott.
"Oh. Hello. Sorry. I didn't think anyone else would be there. I'm Hermione. Granger. We were in school together. You're Theodore Nott, aren't you?" She held her hand out for him.
