I was thinking last night, Why was BB able to speak in the last scene - after getting all effed up and legs ripped off. Ratchet atempts to repair him in the initial prime scene, but he doesn't say a word until Megs is dead. Any theory or answer? Also, what in the world were they thinking when they decided to mobilize the battle into the city with thousands of people and buildings? did they think they were incognito and the Decepticons wouldn't follow ..and they somehow learned a lead and ended up following? I don't understand the logic behind battling in the middle of the desert vs. the middle of a city. I'd like an answer...besides "A city battle looks cooler"
