Wait a minute -- female Sola? That's even better than a female *equivalent* to Sola. Solves all the "hey, I'm not gay" problems right off the bat. You could do it in so many different ways:
Sola: "Say, [CHARNAME], are you into butter-meltingly hot same-sex sex?"
PC: "Ick! Look, I like you, Sola, but not in *that* way. Not that there's anything *wrong* with that..."
Sola: "I see. Eilistraee, grant me your blessing!"
Eilistraee: "Again?"
Sola: "Last time, I promise."
Eilistraee: "Awww, my cute little fuzzy wuzzy. I never could say no to you. Write me a poem, will ya?"
Sola: "Yes, yes."
Eilistraee: Casts Gender Bender: Sola
Sola: Changes Gender
Sola: "Oh, how doth my outlook change/With shifts in body mass and weight/And various appendages/A world bewildering and strange!/Would I not know such w..."
PC: "Oh, shut up and kiss me."
Or if that's not your thing, how about Sola's twin sister? Always teasing him with his poetry, and their common drow heritage. Sort of a drow-Imoen. Speaking of which, she should make lots of allusions to what Imoen did and didn't do in the drow city. :-) The potential for various romance triangles... quadrangles... polygons in general...is simply staggering.
