Pre-CATWS, Steve is working a SHIELD mission where he's supposed to go in as a honeypot for some evil Russian crimelord, but HYDRA already knows about this, so they decide to have the Asset pose as the crimelord just to mess with Steve. Steve, of course, is shocked and bewildered by the uncanny resemblance to Bucky, but he tries to keep going ~for the mission~. It's going along pretty well and is getting hot, then Steve slips up and calls him Bucky. Well, HYDRA programmed the Asset to violently rape Steve if this happened.
