In 725: Home Again, Part 2, Sebastian confronts Eugene with his brother Rudolph about being a copycat. However, when they realize Eugene probably got no money from using their prank, they decide to blame all of their crimes on Eugene. Once Eugene points out though that he is of good character they decide to dump him in an abandoned building. Before they can move Eugene to the car, John Whittaker and Jason Whittaker come in looking for Eugene. When they try to run, Jason subdues both brothers who give up and wait patiently for the police to arrive.
