Why does Sam have no money in DotM? He saved the Earth twice and died the second time doing it. Sure the paid for his college, but why should he have to worry about money anymore? Why wasn't Sam given a liaison position as first contact with the Autobots instead of being shirked to the sidelines with no money and no job? Why wasn't the plot about Sam having the Allspark knowledge in his head not followed up on in this movie? It's not like it just disappeared. Why was Sam given shit when he first tried to enter the Nest base, did no one recognize him, or was it be a dick day? Why did no one give Sam some kind of contact system directly to Nest if something came up? Why did Mearing threaten Sam with treason if he said anything about what he sees in the base? Does the planet still not know about Cybertronians? And I'm pretty sure Decepticons could have found the base assuming they haven't already. Why is Sam the only one capable of motivating any kind of action to move the plot forward?
