I'm just reminded of the letter that Antie Ethel sends in the epilogue where she wanted to "climb you like a tree".
Ethel romance when then?
I guess if they can write/suggest that in, why not Raphael I guess too now.
NO ONE IS SAFE FROM TAV's ROMANCE ARCS
I mean, people want to romance the creepy drider from act 2 - I 'm not surprised, if Auntie Ethel is next.

Let's just romance the "strange ox". He is an overall nice chap and he can polymorph into literally everything. (Plus he almost killed that dragon on the brain for me on his own - Lae'zel helped a little.) Though, considering he picked "ox" instead of "bull" that might indicate a lack of interest.
As for Raphael, having him as a warlock patron could spice up the story considerably in terms of incentive to give him the crown.
