Maybe I can throw Queriel at Gamma and Sesnea/Friel! 8D
Queriel is definitely female bodied as far as seraphim go, but as a seraphim gender and sex don't matter too much. They do not identify as a man or woman, though they do prefer colourful clothes and human fashion, so brightly coloured sundresses and three piece suits tend to be their choices in clothing.
They serve under Zu'hai and met up with Sesnea/Friel after a fight with a chaos.
Queriel is slowly learning about the gender binary, but they don't feel they fit as being a man or woman, and do not understand feeling "out of place" in a body, and barely recognises their own body as being female. It could turn into interesting conversations about gender and sex.
Queriel has no interest in sex themselves, but if Gamma was paired with Sesnea/Friel (and Kyrit wanted to) she could be thrown into the narative to act as just another view point.
Personality wise she is bubbly, agreeable, and follows more orders than they gives. So as far as fighting orders and programming, Queriel would be more inclined to let Gamma go ahead. They might talk about that though, since Queriel is devout to Zu'hai and to following orders, so they might be confused why you would fight such directions.
