When Amy goes upstairs (this scene really really breaks my heart!) there is a capture of the canary (Ava) posing on a ladder with a white background. I know that maybe the ladder is related to Amy's moving to her brand new home but... What does this symbolism mean? Why is the bird on a ladder with a completely white background?
I assume the white background is related to 'being in heaven' or whatever you want to call it. But why does the bird appear on an actual ladder? Wasn't the ladder unnecessary for this particular scene?
