Transformers: Revenge of the Fallen teaser trailer

[Bounty]

Not exactly sure how thats spoiliy, considering he seems to just be Spoiler

Seeing Transformian wirtting

Did you watch that through the end? Spoiler

He reads books in seconds. Whatever Megatron imprinted on grampa travelled down the generations and now appears to make Sam super-smart. Just try to make sense of that.

[Crossroads Inc.]

It's a war. It gives a reason for him to be in the movie. Whether you think he should be in the movie at all is another matter. But, he has no reason to really be there anymore otherwise, given his civilian status.

[Imperial Overlord]

Alternatively,Spoiler

it could be something the Allspark did to Sam, not something that Megatron did to his grandpa.

Which makes more and less sense at the same time, if you can buy what I just wrote.
