There's a short sequence in which Kane (from the game Kane & Lynch) starts a bar fight in the Hope first take portion, in "Great Balls of Fire". Shutting off the electrical switch past the swinging double doors activates the scene. Another opportunity to see Kane comes when you revisit Hope: "Skurky's Law," in the "Hidden Cells" part. Follow the path the guard takes that leads down some stairs and you'll arrive at a vent. Follow the vent halfway to its opposite end and you'll notice the "peek" option, which allows you to watch Kane writing a letter to Jenny (like he did in Kane & Lynch).
