I barely remember the lore. We really need a lore wiki. The Chapos had a riff for a couple of years where they would talk about the necessity of capturing the traitor Gulen and rendition him back to Turkey, and somehow the Chapo fan base got to being called Grey Wolves. I think it was all in reference to a lot of high level collusion, bribery, maybe some light treason going on in the US government and military at the time where people were openly acting as agents of the Turkish state for money. There were a lot of jokes about kidnapping Gulan from wherever he was living in Pennsylvania.

background on Gulen

Here's one of the key stories in that season's plot - Michael Flynn and I think his son may or may not have conspired to kidnap Gulen from his home and rendition him to Turkey

Either way, it's all ironic pitch-black humor. Most of us know the real Grey Wolves are a fascist organization.
