These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fridge Logic: Quite a few cases, but perhaps the most notable - The President was awake when Winter revealed his evilness and while this wouldn't necessarily prove Salt's innocence it, in combination with the many other factors, could easily clear her name.
The Director's Cut explicitly says the President was killed, changing the ending considerably.
The scene where she checks into a hotel under a false name wearing a jacket she stole. Once she's in the room she goes into the bathroom and removes her false teeth and colored contact lenses, demonstrating how she is Crazy-Prepared. At first you watch and you're like "Wow she's a master of disguise! I didn't even notice the (now obvious) fake facial features!!" but then you realise that the reason you didn't notice her disguise is because she looked exactly the same' and was completely recognisable.
But it becomes Fridge Brilliance when you realize that she wasn't wearing those things to disguise herself from her pursuers... she was wearing them as part of her cover, in order to resemble the real Evelyn Salt, the American girl she replaced as a child.
