Oh, I love this prompt, but I have no idea how to start. If they met at a service wouldn't other people notice that he's a gargoyle? What is the nature of gargoyledom? Are gargoyles semi-normal in this universe, a la discworld? Disney's Gargoyles were stone during the day so it'd have to be midnight mass. Maybe gargoyles are secret, but run on weeping angels rules (Tennant-era angels episode, the concept was ruined in the Smith-era). Oh god, Matt would be the first human Foggy would be able to talk to if that's the case. My poor awkward dove!

Wait, what if they meet on the church roof while eaves dropping on the choir practice? I'll be back in a day or so.
