A narcissist is anyone better looking than you are.
You had the existence I could only dream of. Every pleasure at your disposal and you wasted it. You don't deserve this life, Clark, but I do.

That Jewel had everything, turned out what she wanted was what other people had!

Ness, you're so lucky... I envy you. ...I have no luck. But, Ness... well, okay... Let's be friends forever, all right?

"It's all your fault," she interrupted. "If you had not looked so long and admiringly at that Stygian cató"
"Crom and his devils!" he swore. "When the oceans drown the world, women will take time for jealousy.

MELINA PEREZ: "Aksana, you crossed a line tonight. You had no business looking at Johnny the way you did. I hope you learned your lesson and that you will never, EVER try anything like that again. Come on, Johnny!"
Is that Ruby? Why is Jaune with her? They seem closer than usual...More intimate...But, more importantly...W-why I am hiding from them? I just need to talk to Jaune about something, it's nothing personal. I should just approach them, take Jaune to the side and finish my business. Not hiding and silently following them like this. And why is my heart racing so fast? This is truly abnormal.
Love oh love oh careless love
Trusted you now it's too late
You've made me throw my old friend down
That's why I sing this song of hate

She drags him to the door, her arm slipped around his and it burns with how much he loves her touch these days.
The only thing that could make this worse is the boy on the doorstep and the way Feferi throws her arms around him and he smiles and she smiles and it's all so perfectly horrible that Eridan can barely stop himself pummelling this detestable creature into the nearest wall.
Jealousy poisons the mind. It weakens the judgement, perverts the will, and embitters all the emotions and feelings. It makes the end of life a vain pursuit to defeat somebody. If successful in this, another life is wrecked and society perhaps loses the benefit of a well-directed ambition and the good influence of a well-rounded career. If disappointed in this, the jealous mind itself droops in disappointment and vexation, sours on the world, retires to obscurity and finally goes out in rancor and darkness, a practical comment on its own vanity.
