Natasha had been used to being betrayed, to spies and backstabbers, and she often saw right through those who weren't there because they wanted to help.

The exception being you. You had succesfully wrapped her around your little finger, made her fall for you, acting like a perfect partner. When in reality you were spying for HYDRA all the time. You couldn't care less about Natasha or other Avengers, you only cared about breaking them down.

Others had tried to comfort Natasha by telling her that you had most likely been brainwashed by HYDRA and that person she got to know wasn't really you. But Natasha didn't want to hear any of it, she couldn't help but think that she should have known it, she should have seen it. She had sensed it from everyone else, but you just struck right into her heart, clouding her from judgement. She should have pushed her feelings aside, that way she would have seen who you are - what you are. Now she had swore to herself that she won't let feelings interfere with her work partners ever again. She had to fight you when they found out about you, she broke your leg and told you to surrender, when a car pulled up and two men dragged you into the vechile.

And seeing you smirking at her just before the car door slammed shut, she felt her heart breaking into million little pieces all over again because that confirmed her every fear, and she had to let go of every single reason why she still hanged on to you, thought she'd be able to turn your head, that you were just lost and you cared about her, but were too scared to show it in fear of HYDRA.

But seeing you there slammed her right into the face. You never cared about her.
