well i did kinda do up a little bit of that a while back...but hey i like theory crafting and we do have some more info on characterization than back then...kinda...sorta...
Momba is still a gorgon-naga mix, so still doing the stone venom which can be used to make anti-venom for most forms of petrification. (i kinda feel the stone venom is also kinda a nod to the DnD Gorgon (that is not a Medusa) that has the petrification breath, so that's a fun extra)
she started off as a travel writer, and that became more of a foreign correspondent kinda of writing. (i was just watching Degrassi so think Kaitlin Ryan). however, once she became Seth's legal guardian, she had to pause the traveling, and has picked up freelance writing work more locally, thus leading her to covering more high end social events or whatever
thus how she met Nefera. they met at some fashion charity event. as always, Neff had the "oh no she's hot!!" moment, because Momba is a tall muscular snake lady (and Neff is actually kinda tall after all, so finding a taller lady! oh boy! lol). the two of them do hit it off, at the event; Momba talked about her past travels, Neff had plans to go glob trotting after graduation so that is very interesting. Neff does just so happen to "accidentally" bump into Momba a couple days later, since she did mention what paper/news outlet she was writing the event piece for. they meet up a few more times, either intentionally or 'accidentally' before Momba asks Neff out on an actual date.
and from there there was no going back lol. Neff is still a little hesitant at first to tell her family she's dating a woman (because if she'd had a past relationship she hadn't told them then) but, in G3 continuity, they were very supportive. the main point of hesitation was the fact that Momba technically had a kid (Seth); now granted Seth was no younger than 11 when they first meet (because if main cast is 15-16 range, he's 13-14, and who knows how long they've been dating), and again she became his legal guardian...she was up front about having guaridanship of Seth once she formally asked Nefera out though, because yeah having a kid around could be a deal breaker and Momba wanted to make sure that Neff knew she wouldn't be ditching him for her. I'd say the DeNiles approved of that sentiment, and again Seth is a sibling so it's a different dynamic. whatever.
BUT Seth living with Momba has made it so Nefera hasn't moved in fulltime with her yet. HOWEVER, when a too good to pass up foreign assignment comes to Momba (that is a few weeks, maybe a month long), Nefera offers to stay with Seth for the time. so we get Seth and Nefera shenanigans lol. he gets along with her fine; wouldn't be surprised if Cleo has been roped into babysitting him once. and Cleo gets along well enough with Momba too; to be fair both siblings are like "that's my sister's girlfriend, so...whatever i guess". most certainly Cleo appreciates when Momba keeps her out of the house while she's still feeling under Neff's shadow.
and like i said, since Neff doesn't have the fear of her family not accepting her relationship, Cleo gets that now when she starts catching feels for Frankie. (again, watching Degrassi, so Paige's dilemma when she started dating Alex) because her sister's gay, so she'll have to be the one to carry on the family legacy...but again, the parents are far less rigid and more accepting so when she breaks down and admits that, the whole family gets a group talk about how they'll love both the girls no matter who they choose as life partners, so long as the partners are good to them.
eventually, we do get ourselves a wedding, and yes Cleo gets to be the Maid of Honor, because pretty dresses and party lol
but the tl;dr i guess is still, G3 Moffa has far less drama to their courtship because the G3 DeNile family isn't as broken and ridged as the G1 version, but they are still both very into and supportive of each other
