The United States army prepares to invade the Decepticon base. Unknown to them, the Decepticons are already planning to abandon this base for a new one off the Florida keys, intending to make better use of the stolen hydrothermocline to meet their energy needs. Megatron has other concerns on his mind. He is preoccupied with the death of Optimus Prime, unable to fully believe that his enemy is, in fact, dead. This uncertainty drives him mad (as well as the fact that it was a human that did the actual killing, rather than himself).
