So, I read in Tumblr that there is an easter egg in the DVD version of the Black Trailer.

When Blake leaves Adam, the music stops. The next thing that can be heard is a low male chuckling... Is it true? Can someone with the DVD confirm this?

If it's true then what does it mean? Adam is coming back as a villain?
