Newt and Credence are happily married to Percival, but both Newt and Credence's family think Percival is taking advantage of the two younger men. Either together or separately, Newt and Credence's families start to interfere in the relationship. Like maybe Newt's brother keeps cutting in on his time with Percival by saying he needs help with stuff, or maybe a not abusive Mary Lou starts introducing Credence to men she thinks are more suitable, like maybe even Grindelwald. Newt and Credence are oblivious to it, and so is Percival in the beginning, but he isn't the Director of Magical Security for nothing, and soon he figures out what is going on. Newt and Credence's families also start to whisper a few white lies about Percival too, not anything too outrageous but enough to have Newt and Credence doubt some things. Percival, who doesn't have any close family to support him, starts to feel very alone.
Their plan starts to work as things begin to go awry between the three husbands. Percival tries to get Newt and Credence to see that their loved ones are manipulating things, but they don't believe him, trusting their families. It gets really, really bad to where a separation is imminent, much to Newt and Credence's families satisfaction. But then something happens, like maybe a fantastic creature goes on a violent rampage or Grindelwald attacks them all. In any event, Percival is the one who throws himself head first into defending his husbands and their families even though they were treated him like dirt. Percival nearly dies saving everyone. Newt and Credence are heartbroken and want their husband, while their families are guilt ridden and ashamed for not seeing how good a man their sons have. Percival lives, but he is beyond pissed and hurt, to the point where he tells Newt and Credence that he wants a divorce and to have nothing to do with them, or their stupid, heartless families. Now Newt and Credence, and their respective families have to do everything they can to keep Percival. Make them all extra, extra guilty and have to work for it.
BONUS: This can have mpreg in it too, like maybe Percival gets pregnant in the midst of all the drama and just adds another layer of guilt.
