Fred didn't know Penny all that well. Sure, she was a member of the Order now, but that was yet to be tested, and sure she'd dated Percy for a while, but that hadn't exactly done much to put her in the twins' good book. She'd taken points from them before, but so had every prefect and professor, so that didn't really count either.
When he thought about it that way, this might be the first time he was really having a proper conversation with her. Fred thought about that, then shrugged the thought off when he heard the knock at the door, he'd only booted out the last customers fifteen minutes or so ago.
He went down, unlocked it, and let her in. He was dressed the way he always was for work - outlandishly bright blue suit that did nothing but clash with both his hair, and the bright green shirt he was wearing with it.
"Clearwater, come on in." He flashed her a wide Weasley grin, and stepped back to let her inside.
