Lily smirked, shaking her head slightly at the idea. "I'm no more your redheaded firecracker than you are my fashion-challenged rascal," she pointed out, but there was no ire in her tone, and she shot him an amused glance before taking another swallow of her drink, letting the telltale warmth spread through her. It was comforting after a day like today. A week like this week.
The comments about James and Marlene got a relieved nod from the girl; she'd been expecting Sirius to want to talk about one or the other, either to try to change her mind about the former yet again or grill her about the latter. Neither of which would have been comfortable conversations.
When he revealed his true motive, though, she went momentarily still, then sat up straight from her slouch and looked over at Sirius, balancing her goblet carefully on the arm of her chair before speaking, her words slow and deliberate. "First and foremost, one remembers than blood isn't destiny and the behavior of others doesn't have anything to do with you, even if those others are your biological family," she murmured, catching Sirius's gaze to show that she was in earnest. "And then...then one figures out what he or she can do to reverse the damage. Or combat it, or amend it, or simply stop it happening again. And if one...you...know anything that could help any of those things, you tell Dumbledore what you know. If not, you...do what you can. Has Ja- Potter talked to you about. Um. The get-together tomorrow night?" Which was the best subtle way that Lily could think of to reference the meeting with Dumbledore; even in the Gryffindor common room, she didn't want to say too much about it, just in case. Hopefully Sirius would catch her meaning. Assuming he knew about it at all; but James had said he wanted to bring the other boy along, and so he must have mentioned it to him, surely. Lily had her misgivings about Sirius being involved- she wasn't convinced he could keep a secret to save his life, or be serious about anything, but when he'd just asked such a question, suddenly it seemed unfair to keep him out of the whole thing.
