I will note that I'm primarily a ftb writer but, once I'm comfortable with someone, I can do more if it fits the line! Not that he wouldn't be willing/able/want to, I'm just letting you know my personal preferences first!
I'm picturing him as Captain of the Ballycastle Bats as a Chaser. He probably didn't want to sign up for the bonding but was urged by the request of his manager/the ministry that someone in such a position as public as quidditch sign up to get others to as well. I would love for a tentative start, perhaps with an open-ish marriage for the first while but as he spent more time with her and put aside his begrudged nature, he was far too possessive to want to share her with anyone. He would be all for starting to try for a child, semi worried in the back of his head that he was affected by the Curse somehow (though, that's not the case!)
I'm open to Joseph, Paul, or even Nathaniel Buzolic. Is there one of the three that you prefer?
