Let's say Hydra has a pseudoscience device that can download memories from one mind to another. Let's also say that Steve has a mishap with this device and gets a ton of memories from a Hydra agent (imo Rumlow would be the most interesting but I'm flexible).
Included in the download is many memories of the agent raping Bucky.
+ this really fucks Steve up and makes it hard to be around Bucky
+ this really fucks Bucky up once he learns about it
+ it fucks their sex life up
+ there are some small but noticeable changes in Steve's behavior and mannerisms, since the agent's personality is inside him now
memories can be a problem if they're the wrong person's
