[Avengers: Endgame] What did the agents think went on with Captain America?

When the Hydra agents heard Captain America swear allegiance to Hydra, what did they think happened?

After all, he defeated the Red Skull and foiled his plans, and he’s been in the present only for a short time.

How did they think he got recruited to their side?

None of Captain America's public actions were counter to HYDRA's goals. Even the one time he espoused that he would not work with SHIELD because they had HYDRA tech, he didn't actually hurt HYDRA in any way. Defending New York didn't hurt HYDRA either. Even a mid-level HYDRA agent might easily conclude that the real Captain America was never found, that HYDRA created a clone, or a body double and 'planted' him in the ice to be found and recruited into SHIELD. It is a simpler explanation to a HYDRA agent than 'accidental cryostasis'.

So... yeah. He's a plant they all decided, relieved to know they'd never have to fight him in an elevator.

Actually, if Cap did not create a new timeline, then they would get into the elevator knowing that he knew, which explains why the did such a bad job of hiding that they were there to detain him. So it's not a continuity error in Winter Soldier.
