Honestly, I wanna know what your guy's favorite minor character(s) are.
Mine are Shaw and Gabriel (though he's not exactly a minor character)
I liked Shaw because well... Navy, plus his chemistry with Raven, and in the group of these people outlined to be antagonists, Shaw was the friendliest out of them. (besides Diyoza.)
Gabriel was my overall favorite, he was basically Madi's uncle and I found it pretty devastating when he died, especially since it was so close to the end too, he was pretty badass too.
