First Episode had a funny line
Robert Patrick(who played T1000 in Terminator 2) says a Sarah Connor-joke.
Langston correctly identifies Castro as the name of a famous Yankees player, confirming the moniker is likely fake, but when asked, "Who's Sarah Connor?" Reacher season 2's main villain responds, "I don't give a sh*t."
Sarah Connor is, of course, the name of Linda Hamilton's character in the Terminator franchise, and Terminator 2: Judgment Day saw her hunted down by the liquid metal T-1000, played by one Robert Patrick.
