Assuming Trouble is also keeping Jeanne then the Gryphon family is near packed. There's room for probably two more children, but they would have to be a bit younger logically and ready to accept three (or four) elder siblings and the given family history. Alternatively the Noble had brothers (who died for varying reasons) and you might be one of their children I suppose?
Either way I've been keeping track of the family lore so far and will be adapting it unto Liar's new world when it comes. If you'd like to be a Gryphon or are just curious about the family for the purpose of making your own separate character let me know. I'll fill you in on present details.
I feel you man. Get well soon.
Well, Missy might not rejoin this right away, given her sporadic appearances of late. And if she does she may not use Jeanne 100% as she was. In all honesty, I would recommend (and this goes for everyone) that anybody remaking a character should just remake them without counting on the reappearance of formerly established siblings or buddies. This makes it easier for new people to find spots in the RP they like without having to worry about things like "Well if the Gryphons are full, I guess I can't..." and it also lets old hats have the freedom to do something completely different and not worry about your expectations.
