Natasha is the only person who understands what Bucky went through. Nobody else can even relate to or understand them. They literally have shared life experiences, so Marvel I need a relationship out of these two ASAP. Trust me it will be great for both of their character developments. Natasha can teach Bucky how to cope with the stuff he has done and help him to the path of redemption. They wouldn’t have to hide their feelings or emotions from each other and they can both find comfort within each other that no one else ever could, they also won’t be afraid to talk about the thoughts that are running through their heads because they know that they have both been through the same experiences, they won’t judge each other for the things they have. There are a ton of other reasons this relationship needs to happen, so Marvel how about you get to work on that.
