Hi Dank,
I think, it's a great example how the conspiracists work. They ask "why does it get brighter?" and prove that they have done zero research because if they do, it is easy to find out what happened.
And yes, you see reflections of Aldrin in the window through which the camera is looking.
To give you an idea, here's a photo taken during the trans-lunar coast showing the window and the camera:

Recognize the reflection of the camera in the window.
