Sirius took in her mock offense and responded with a hugely dramatic pout.
"How inconsiderate of me! Please, fair Lily Flower, accept my humble apology!" He let go of her long enough to do a very complicated sitting bow.
"Don't worry though, you're always going to be my first and favorite Lily. Lilu just sort of, gets it." A combination of her already very Jamesish personality mixed with her intimate knowledge of Sirius' life maybe...
"I haven't really gotten to know Other James and Other Albus yet though. Other James seems like a lot of fun, but I'm not entirely sure I've even met Other Albus yet. Maybe in passing. How are those Potter Family lunches going? And yes, before you ask, I am terribly jealous that I've never been invited." He smiled, passing it off as a joke, even if he was secretly a little dissapointed about that.
