(Super long theory that had to be split up part 1) Here's a theory: a gray sleeve appears at the end of the Lil Cal flash. The color of this sleeve, if you check in Microsoft Paint (the name of the site... Hmmm...) has a hue of 160, a luminosity of 56, and 60 as the red, green and blue value. That's three 60s. What else has three?
