I never understood, yes the rest of the Team may have been undisposed of at that moment, when the Miko, Raf and Jack informed Ratchet that school has been over an hour ago. Like Miko insisted, why didn't Ratchet himself went to pick up the kids, or simply told the kids to go somewhere where they can't be seen and ground bridged them to base, but instead Ratchet simply avoided them and hang up on Jack. Having Ratchet either ground bridging them or picking them up, the kids wouldn't have been captured by the Decepticons and the Autobots would of have used the Omega Keys to activate the Omega Lock and restore Cybertron. It's not like Ratchet could of done anything to help Optimus from their base. Any thoughts?
