what bugs me the most is the fact that Scooter was the photo inpector and politely pointed out his doubts to Amy. They got to the bottom of the matter quickly and painlessly.
Then, out of the blue, we are graced again with the presence of someone lurking in the dark. Making a bigger deal out of the fruits of someone else's microscope work. Bringing the matter into the spotlight, acting as if they were the one to have solved the mystery, albeit nearly 4 hours later.
NOTHING was obvious to Microbabe, whoever that may be.
