Not to get ahead of my own future fics but like. I am getting visions of the future once Abby and Trinity sort their shit out and so do Mel and Frank. They are going to be the weirdest most impossibly well-adjusted vaguely toxic quad of non polyamorous but weirdly intertwined soulmates/exes/coparents/blood brothers.
Trinity and Frank go jogging together after they both get kicked out of a run club for being insufferable. They both have that app where you can log the beers you drink like Goodreads and they're each other's only friend on it because Mel and Abby both hate beer so like. They have no CHOICE but to be beer snob buddies they have no other option!!! They both love roughhousing around with the kids at family parties and regularly beat the shit out of each other with those balloon baseball bat things.
A patient calls Trinity a bitch in the parking lot during a shift change and Frank gets a gash on his forehead when he gets in the guy's face and tries to make him apologize and the guy punches him instead.
"Man, who gives a fuck what he said!" Trinity snaps at him, after security has intervened and she's dragged Frank back inside and into a room. "I am a bitch, you dipshit! C'mere, let me stitch your stupid fucking head wound."
"Fuck no, you and sharp implements are not allowed anywhere near my body. Mel, baby, you'll stitch it, won't you?"
"Oh, gag, you are so insufferable--"
"Fuck you, Santos, I got wounded defending your honor--"
Someone in hospital admin makes a disparaging comment in front of Trinity about Frank's addiction and suggests he shouldn't have been reinstated and Trinity has to be physically held back from keying her car, Mel barely managing to drag her away, spitting mad and reminding anyone who will listen that she knows Krav Maga and isn't afraid to use it on some old lady if the motherfucker deserves it.
Meanwhile, Mel and Abby do a book club together and love to gossip loudly about how Frank is in bed while Frank and Trinity both scream and both try to cover Trinity's ears. They take naps together in the big king bed in Abby's house with the kids snuggled up between them, Mel's white noise app playing rain sounds and Abby's diffuser spewing lavender.
They go grocery shopping together and work with Becca to ruthlessly plot out perfectly strategized Sam's Club > Aldi > Giant Eagle itineraries to optimize sales and deals across two households with a laundry list of dietary restrictions and picky eaters and meal prep requirements.
They take the kids swimming in Abby's parents' pool and Mel helps the kids float and demonstrates proper techniques while Abby cries and takes a million pictures and videos and Trinity and Frank try to drown each other in the deep end. After the kids and grandparents go to sleep they go back in the water and do chickenfights and Abby and Frank play volleyball way too competitively for 1v1 in the shallow end of a residential pool while Mel and Trinity chase diving sticks and play mermaids on the other side.
They wander into each other's houses like weird sitcom friends and coordinate movie nights and concerts and dinners out both with everybody and in variable pairings of all configurations, Abby and Frank, Trinity and Mel, Frank and Trinity, Mel and Abby, all with their own inside jokes and stupid memories and special bond that can't be replicated anywhere else.
Like they are so insane but they are a family I don't make the rules they're just like this.
