Ratchet needs answers, before the crisis on Earth escalates, and that means sending a crack team deep—literally—into enemy territory. Too bad then, given Ratchet's oath to protect human life, that his available resources amount to Verity, Hunter and Jimmy. Too bad also that Decepticon unit commander Starscream is intent on removing all evidence of his indiscretions, and that includes the particular bit of ‘enemy territory' in question. Enter: Blitzwing and Skywarp!
