A what if situation. ??Trigger Warning?? Toxic crazy ex.

Cosmos never shows up in canon. This is all a hypothetical what if she did.

Cosmos would make his life an absolute hell. Having been betrayed by her ohhh so dearest lover and imprisoned for a few millenniums. She's bent on revenge for what he did. Effectively ruining her thrill, the enjoyment of utter malice and her life by putting her in prison. Oooohhh how she's missed her little pookie bear no one else can have him except her.

I envisioned this happening when he was 4 months shy of having his daughter. After a rocky start to his parenthood to eventual true desire to have his child he had been looking forward to it. That is until she comes into play. Her presence would absolutely derail him. From past experiences she was physically and mentally abusive, gaslit him, controlling behavior, belittling, blaming, jealousy you name it. The most vile creature hes ever had the misfortune of dating back then all came back to him in one foul motion the second he heard her voice.

"it's been a long time Discord, my dear" she had broken into his house when he wasnt home waiting for him. When he teleported inside after being out doing something for the mane 6. He stood straight up stiffened wide eyed in abject horror, his hackles raised, ears pointed back, wings out stretched. He had his back towards her when she was speaking, instinctively he used magic to conceal his pregnancy in the hope she wouldn't know.

"Oooh come now my dearest how stupid do you think I am? I know what you've got there"

He had an overwhelming urge of fight or flight in his mind though it wouldn't help anything and she'd find him. She knows hes afraid of her uneasy, weary and a coward she expected him to run or submit. He turned around asking what the hell shes doing here before telling her to go back to the black hole she crawled out of. Surprised he actually had the gall to talk back and confront her this was new she knew he was playing an act he is far too much of a coward to do anything to her. She could break him

He let out a deep gutteral growl his voice got extremely sinister "Piss off I want nothing to do with you"

To shorten my hypothetical situation here...

This would not end well and they'd end up in a real physical altercation something he probably shouldnt be getting into when hes roughly 4 months away from having his child but he isnt going to back down from his abuser either.
