Factual error: The Autobots/N.E.S.T. base is said to be on Diego Garcia, a real military base in the Indian Ocean. The island in the movie is not D.G. The movie version appears to have hills and sparse vegetation, the real island's a tropical climate, and the highest point is about 22ft above sea level.
Continuity mistake: Near the beginning when they're in China, the NEST team is moving on a Decepticon reading and it should be right in front of them.There's an overhead shot and a shot looking into the concrete tubes to where the very large Decepticon is, but you can't see its vehicle form at all until it starts transforming and attacking the troops.
Continuity mistake: When Sam and Mikaela are in the evening desert scene the night before the big fight, Mikaela has a cream colored spaghetti strapped top on. When the scene cuts back to them, she now has a black spaghetti strapped number with a black scarf around her shoulders. Cut back, and the beige shirt has returned.
Continuity mistake: In the party scene when Sam is standing and holding his drink, every time it switches angles the amount of liquid in the glass keeps changing. First it's full. Next it's half empty. Next it's almost full again.
Revealing mistake: The same shot which shows the sun is used several times in this movie - please note the cloud next to it. Two of these shots have Jetfire in it, and three are after that.
Continuity mistake: When Alice and Sam are driving away from the party in Bumblebee after she gets squirted with "fluid", we see that they are driving down a city block. Each subsequent shot out the side windows from inside the car show distant blurry lights - not buildings we should be seeing.
Chosen answer: He knows from stories passed down to him from older generations of bots, not much unlike stories about the past passed down to us from our ancestors. His line about no one telling him anything is just a way to avoid being put back in the box or being tortured by Mikayla.
