There is a villain in the game named John Gilnitz. John Gillnitz is an amalgamation of the names of show writers John Shiban, Vince Gilligan, and Frank Spotnitz. The name was used for seven characters throughout the shows run.
When recording their lines, the cast all wore the same red lipstick as seen on the "behind the scenes" footage, which is concealed as an option in the game's submenus.
There are no specifics offered, but some time late in the seventh season.
