Very early in the series, a biker jump over a bridge causes a main character to fall off and become unconscious. He becomes fine afterward.
Three men attempt to attack a man on his bike, until they get interrupted by another man. They then attempt to attack him, when a new man fights them off.
In episode 2, a man is pushed into a room and locked inside.
Episode 9 has some characters being exposed to some booby traps, resulting with one of them getting hurt in the leg. This episode, and episode 10, have characters fighting or getting attacked.
Episode 13 has a rather comical scene in which a man attempts to punch another man for being fooled at for the whole time.
