Hi Dea, welcome to the game. I'm Caroline and I have three characters.
This is Charlie, her brother in law. He's back in London and has opened a club thanks to losing part of his right leg to a venomous dragon bite. I imagine he likes her a lot, and adores her children. He's pretty good with children as long as he remembers not to swear!
Dean Thomas (artistdean) has a pretty heavy (but well managed) dose of PTSD. He's a trained artist and works part time at the pub. He remembers her from the Triwizard and Shell Cottage, and likes her a lot. Trusts her more than some people I imagine.
Gwenog Jones (haveyoumet_) is probably of least significance. She's an abrasive, flirtatious, prickly Beater and Captain for the Holyhead Harpies. Probably doesn't know her at all.
