I haven't talked to Mayo, either... The only person I really talked to was Katie a few times. I'm bad at staying in touch with people. Sorry, loves. I apologize. :(
Lily started fixing that, didn't she? She and Cass already made up... And James. And Sirius. So I think she's good to go! She doesn't have to apologize to Remus (I don't think she does...).
As for Andie... Andie says that James can try to be Sirius' knight in shining armor, but he'll have to get to him before her because when it comes to Sirius, Andromeda will stop at NOTHING when it comes to Sirius. But that's because she doesn't have real friends 'cept for him.
Andromeda: HEY! Me: Isn't it true? Andromeda: Well, maybe... But that's beside the point. Me: Uh, no, it's not. Andromeda: Whatever.
