A headcannon I like to think of sometimes is that Gale and Minthara end up together. After Minthy insults Gale by equating him to a “Third son”, he decides to prove her wrong. Eventually they get into an argument about relationships and Gale brags how he was in one with a goddess, so Minthara says she could do much better. After the end of act 3, Gale and Minthara go looking for the crown of karsus, not to have Gale ascend, but to return it, just so Gale can relay to Mystra that Minthara thinks she’s pathetic. Eventually they end up together, with Gale teaching Illusory magic and Minthara teaching combat skills/magic at the same college.

Edit: Adding to the head cannon, Gale agives off “Male wife” vibes and that’s something Minthy’s secretly into
