You are a lowblooded troll that revels Eridan as royalty and have been appointed to him as his 'knight', ready to be commanded without question.
You met young, maybe even before he met Feferi, and you two are fucking best friends. You’ve lived together in separate hives on the same island, your’s being a little hut that you only ever go to sometimes sleep in. You truly mostly live with Eridan. It’s one of the reasons he’s stayed above ground, despite being a sea dweller. You can’t live underwater, and he needs his servant.
Now I’m thinking of cute shit. Like secret cuddles that only happen when you’re both alone in his hive. On nights when Eridan gets too dramatic for his own good and starts crying, you know just what to do, how to hug him, how to stroke his hair and what compliments to tell him to bring his ego back up. Eridan lets it, melts into your touch. It’s a normal thing for you that Eridan would never let anyone know. Not even Feferi.
There’s no one that knows Eridan better than you, and there's no one you have time for other than him. Even with both of you acknowledging your codependence, Eridan disregards giving you his pale quadrant; his feelings are focused on someone else, “Feferi is my best fwwiend uwwu My moiwwal <3”.
It's ok.
You are completely fine with your place in Eridan’s life. You've bought into the caste bullshit and even through your blinding love for him, never once saw it as a red feeling. You just saw it as your ‘duty’ to your prince; never allowing any romantic thoughts with him. You just want to help. You just want to make him happy.
Still, your relationship is part of what made Feferi so uncomfortable and led to her leaving him, because whatever he did, wherever he was, she knew you would be there too, even contacting her and giving her advice on how to deal with him when she had trouble. She tried using this to her advantage, during all his genocidal ramblings, Feferi would remind him how there’s trolls he doesn’t really want to kill, friends he enjoys.
Like you. It’s the perfect example, but you idiots always shrug it off as a problem of the future. Eridan doesn’t want to think about it. And you… pretend to think the same. But you know in your heart. You’ll probably die one day. This drives Feferi MAD. She liked you, and she liked Eridan, but she did not want to be stuck curbing off a genocidal maniac and his enabler forever. It’s extra work!
The break up, honestly, is hilarious. Eridan’s first thought was to yell for you to come to his room and as you stumble in, he has the most pathetic face and screams, “SHE BROKE! UP! WITH! ME!! ”
You comfort the shit out of him after this. It becomes a whole thing for the whole night; you give him ice cream and snacks and let him cry it out on your shoulder. Suffering through the fallout through the rest of the session. Eridan still fails to connect with any other troll. His negative thoughts continue fester. But you're with him. You continue trying to get through to him, to move on, to let go but-
Your story will end in tragedy. You could see the escalation, you disagreed with his plan to leave but you could not get him to listen. His duel with Sollux is the same, but as Feferi and him ready their attacks, you get in the way. You've been struck. Eridan is shaking. Crying. Frozen in fear.
He immediately drops his wand to hold you as you bleed out.
You've been hit in your vitals. You’re in incredible pain, even slurring blood as you talk. But you must. You have to apologize for dirtying his cape with your 'ugly blood.’
You’ve always had a COMPLEX over your blood color. Never wanting to bleed in front of Eridan for fear of his look of disgust.
But for all your caution, here you were, bleeding out all over him. And in your final moments, your hazy mind thinks the reason he looked so shaken was because of that. Your horrible, cursed blood. Not because you were his everything. Not because he’s in pain for you. The thought that you were loved did not cross your mind.
Eridan survived. The other trolls survived. He goes on with the session, and will repeat those last words in his brain forever. Realize that his talks got to you in a way he never intended. Crumble under the guilt as he internalizes that you wasted your last breath, your last words, for something so idiotic. And it was his fault.
He will cherish your blood color from then on.
For the first time in his life. He is truly alone. Just in a daze. Unable to properly take care of himself because he was so used to your helping hand for everything. A sad little pampered fish boy, having to learn how to live on.
