This was the night Farrell filmed the show’s shocking finale, which sees his character Oswald Cobb murder beloved mentee Victor Aguilar (Rhenzy Feliz).

It’s brutal and unflinching, with a shock factor up there with some of the biggest TV deaths this century – the likes of Christopher Moltisanti, euthanized by his “uncle” (actually his cousin) Tony in “The Sopranos,” or Hank, Walter White’s brother-in-law, caught in the middle of a hit gone sideways in “Breaking Bad.”
