OKAY SO this started out on accident, but grantaire has had a lot of friends here who were monarchs in their homelands. by this point, he might purposefully be befriending as many monarchs as he can. partially to prove a point to enjolras, but you know, HE'LL BE YOUR PAL, MARG. he's already friends with loras and he was friends with renly.

and he'll 100% get along with her better than theon will
