Why were the killer gorillas suddenly fearful of Amy?
The scene where Amy saves Peter never bode well with me. Aren't these the same gorillas who can easily kill a full grown silver back gorilla with their bare hands (including Amy's parents)? Aren't these the same gorillas who could outsmart a camp full of humans with militarized weapons and technology?
So why fear a runty little gorilla like Amy?
I get that her talking device might have caught them off guard, but I never understood why they treat her with such deference when she comes to Peter's rescue. Seems out of character for them.
