Its the point in the film when Sam, Mikaela and Sam's new room mate are running away from the Decepticon disguised as a young blonde girl..they run out of the college and dive in a silver car which Mikaela hotwires, as she's doing this im pretty sure Sam looks up and says something like "MEGAN she's almost on the hood!" instead of "Mikaela she's almost on the hood!" Also who was the Decepticon helicopter that picked up the car? He was never seen or mentioned again.
