After three and a half hours, Sam managed to find the front doors, and, after he sprinted through them in relief, a large group of soldiers and seven Autobots that appeared to be attempting to look inconspicuous.
Sam sighed, knowing what was coming, and made his way over to them, noting that the cars, especially a certain yellow Camaro, looked far too relieved and that the passing civilians were giving them odd looks.
"Where the hell have you been?" Lennox demanded.
"Inside, the exhibits were really interesting," Sam quipped.
Epps suddenly began to smirk, "You got lost, didn't you?"
"Shut up, Epps," Sam muttered, marching over to Bumblebee.
"How is it possible to get lost inside a museum for nearly four hours?" Lennox asked incredulously.
"Talent."
