Sideways is killed by the Autobot Sideswipe, while Optimus Prime kills Demolisher, but not before he warns them of the Fallen's return . At NEST's secure headquarters in Diego Garcia, National Security Adviser Theodore Galloway concludes the Decepticons are still on Earth to hunt the Autobots, since Megatron's corpse is at the bottom of the Laurentian Abyss and the last known AllSpark shard is secured in the base . Soundwave hacks into a military satellite, overhears the information, and sends Ravage to retrieve the shard . </P> <P> Meanwhile, Sam Witwicky is preparing to attend college, leaving his girlfriend Mikaela Banes and guardian Bumblebee behind . He finds a smaller AllSpark shard and picks it up, causing him to start seeing Cybertronian symbols . The shard's energy pulse turns the appliances in the kitchen into murderous Transformers, who attack Sam and his family . After Bumblebee destroys the rampaging appliances, Sam gives the shard to Mikaela, who later captures the Decepticon Wheelie when he attempts to steal it .
