This Prime speaks of how they have watched him for a long time, and that this is and always has been his destiny, praising him for his natural talent for leadership.
2. There is a scene like a flash back where it shows a civil war between the two factions and The Fallen on top holding the Matrix. Whether they fight him or not is unknown but we are lead to presume they did because the following scene speaks of how they recaptured the Matrix and hid it from him.
3. I found him to be more scary, yea.
4. No he does not and let me tell you, I was hoping he would but in hindsight I'm grateful he doesn't. A lot of them speak and crack jokes throughout the movie - leaving Bumblebee as the way he is gives him irreplaceable charm that makes him easily the most likeable character in the film. There is a scene with Sam and this "girl" in the car with him, and let me just tell you, you will not laugh as hard for a long time.
I find Bumblebee the most charming robot myself. The voice thing is clearly in his favor and its a nice touch from the producers.
Thanks man! I am so looking forward to seeing all this for myself!
