I actually could’ve done without Hawk’s turn. He’s a strong, believable villain. Heading into season 4, Kreese only has Robby and perhaps the leftovers who lost the big fight in episode 10. Robby’s arc didn’t seem to intersect enough with the main storyline of season 3 (especially as it relates to the other teenage characters). Keeping Hawk with Kreese would’ve balanced the two sides a bit more.
