James-Dean and Angelo having couple arguments would be so angsty, funny, and just an overall emotional hurricane. Both of them have trouble talking about their feelings and figuring them out, so having healthy conversations and communication with each other is something they BOTH need to figure out, but until then, their fights can be volatile and borderline violent. They also become EVERYONE ELSE'S PROBLEM WHEN THEY'RE UPSET AT EACH OTHER. For Angelo, he does get frustrated with James-Dean occasionally due to his clinginess and possessiveness (he can never decide if he loves it or hates it) and maybe one night, he and James-Dean get into it because Angelo's being overworked and he feels suffocated by James-Dean but James-Dean thinks Angelo is falling out of love with him because he's so angry and he clings EVEN HARDER to the point that James-Dean is WRESTLING TO GET INTO ANGELO'S ROOM AND ANGELO IS NOT HELPING BECAUSE HE'S JUST ALL: "WHY DID I EVER LOVE YOU IN THE FIRST PLACE!"
James-Dean: "MY ANGEL, DON'T BE CRUEL. PLEASE!"
and Angelo just manages to shut the door and James-Dean is crying and begging for him while Angelo just yells back at James-Dean. Eventually, Angelo wakes up earlier to leave for work because he does feel bad that he treated James-Dean so horribly but he's also still frustrated with the way James-Dean was acting. So when James-Dean wakes up, he immediately goes looking for Angelo and when his butler informs him that Angelo left early, James-Dean just being all: "Oh...okay..." and then he goes to his office a cries a bit before he also gets ready for work. ANGELO JUST BEING MORE SILENT AND BROODING THAN USUAL, if Troy greets him even slightly too loudly then Angelo will give him HIS MEANEST glare, and even Lisa doesn't antagonize Angelo because she can tell he's not in the mood. Meanwhile, James-Dean just being all mopey at work as he sighs loudly (wanting someone to ask him what was wrong), and if someone DOES ask, they get a long winded lament of how Angelo treated him so cruelly but how James-Dean still loves him and Venus, Kitty, and Jack just side eye each other while Edison and Ramone are all: "Yeah, HE'S the problem. We don't think you overreacted at all."
And like, when it's time to go back home, Angelo sending James-Dean a text that he's going to stay at his house tonight, ONLY FOR HIS PHONE TO BLOW UP WITH TEXT MESSAGES AND PHONE CALLS. And even Angelo mutes them or ignores them, James-Dean literally spamming him on EVERYTHING and creating burner numbers and he just rolls his eyes because he will not be able to get any sleep like this so he rants to Warden and Vincent on the phone and Warden and Vincent give him...pretty solid advice.
Warden: "Yeah, Ronnie is crazy as hell like that too. If I don't give him his morning goodbye kiss, he thinks I hate him."
Vincent: "Robert can be the same way. I had to use tone indicators over text because I have "dry responses", apparently."
Angelo: "So what do you two suggest I do?"
Warden: "Don't ghost him and ignore him, that's gonna make it SO MUCH WORSE."
Vincent: "Definetly take some time to write down your feelings and what you want to tell him...and then it run it by someone to try and make it nicer. That's what I do."
and they give him some other advice so Angelo just drives back to James-Dean's house and James-Dean is already opening the door before Angelo has time to knock and James-Dean is all: "...Dr. Santos."
Angelo: "...I got these for you." and he hands James-Dean flowers and James-Dean just staring at them before he makes a snide comment about how they look a little dry but he takes them and he's all: "Well, I suppose you can come in."
Angelo: "You were the one who blew up my-" and then he has take a deep breath before he's all: "Thank you." and he follows after James-Dean and James-Dean is 100% giving him the silent treatment until Angelo wraps his arms around James-Dean's waist and cuddles into his neck.
Angelo: "...It wasn't my intention to make you feel unloved. I was just frustrated and I took it out on you. I know that you need a lot of reassurance but I also have the right to be able to feel upset without worrying about if you feel like I still love you or not..." and then he kisses the back of James-Dean's neck: "The answer is always: "Yes", by the way."
And James-Dean just relaxing in Angelo's arms and he leans into him as he's all: "...Thank you for apology."
Angelo: "James-Dean Dent."
James-Dean: "Alright, alright...I'm sorry I chased you down the hallway even though you needed some space...I don't really have an excuse aside from the fact that I just love you so much and when you're upset...I feel like I failed to keep you happy."
Angelo: "I'm never happy...aside from when I'm with you."
and James-Dean smiles and turns around to kiss him and Angelo kisses him back softly.
