As any good amateur scientist worth their salt knows, you need to have evidence of your experiment - in case something goes wrong. So Joel walks over to the camera that was next to the mirror and leaves the other ones recording, for now. Then she brings it over to her computer and hooks it up. She watches the video and sees the change occurring in real time. Since she knew before the experiment that her appearance might change anywhere from nothing to... this unexpected development - she, he at the time, had collected photographs of himself throughout his life - his first birthday, his first school photo, the photo of him holding the first place trophy for the fourth grade spelling bee, the photo of him coming in first place in a National Science Fair at the age of 13, and photos he had taken of himself in the weeks leading up to the experiment - both clothed and unclothed.
None of them changed.
