"Why are you so calm about this?"
She had been calm and steady, her expression neutral the entire time. Which had been a while -- his efforts to try and find the right words for this had taken a while. Vaguely, she wondered for a moment how the others had ever gotten it out of him in the first place. Then it hit her. They hadn't. The Marauders simply hadn't waited for him to come to them to explain, like she had. They'd figured it out on their own, and like the bumbling, overly eager dolts that they were, lumped themselves onto Remus with their own revelation, and probably held on for the ensuing ride for dear life. ( Why could she imagine them all laughing the entire time as they struggled to hold on? Like it was one of those American Western bull ride things. )
It was probably what he'd needed from them, but what he needed from her was something all together different. She'd known that for a long time. As long as she'd known the other thing, too. Thus she had waited. & waited. & waited. It was hard waiting, and maybe she'd gotten a little impatient and forgotten the order of these things, the proper order they needed to have happened, so the first kiss had happened before everything else, and then she'd flashed her hand of knowing way too soon. She might have been able to stop him from running away completely, but he'd still pulled back in a way she was painfully concious off.
So she had made a daring move. Bribed Peter to bring along a chunk of her mother's peppermint fudge on whatever adventure they went on every month ( they were so unsubtle about it, really, it seemed a miracle to her that more people didn't know ) with the promise that if he gave it to Remus, she'd put in a good word for him with Sarah. Sure enough, a few days after the full moon and found Remus returned to classes, and then had him finding her up on the Astronomy Tower at sunset. He'd started to explain, and she'd just stayed quiet, open and understanding, as she'd planned on being since the start. Lily know it wasn't what he would have expected, he expected the worse, but that was why she couldn't give it to him. That didn't make the question any less surprising though.
" . . . because I've know. It's not a surprise to me, Remus. I was only ever waiting for you to tell me yourself. In your own time." Lily gave him a soft smile, not at all threatening. "I didn't expect it to take so long. I shouldn't have gotten frustrated, I know, but " This was the hardest part. " but I couldn't let you turn away a chance for, for something, just because you don't think you deserve it."
