Jimmy Fallon vs E3 Last of Us demo...exactly how much of it is scripted?

That was sad. So scripted that I want to puke. And ND are officially liars now.

In another demo they showed the press, the same section was played out completely differently. 

And the almighty Hideo Kojima is a liar too.

 

Anyone noticed how in the Jimmy demo Joel had one round before running out unlike the E3 where he had no ammo to shoot the final guy before being bricked?
