Addendum.

The very next time I saw my one (Pentecostal) (Guatemalan) coworker -- the third time since he'd returned -- I said hello to him as if he was a new worker with the same first name as me, to play off the bit of the schtick that he'd started during our last interaction, but with that he told me his real first name, and though I tried to say he was "el [his first name] segundo," he seemed tired of the joke, and he said he was the same guy, and that was that, and he went back to whatever he was doing.

Done.

Or, as they say in Spanish, "Finito" ('Done').
