From the caption of the teaser on the VBS site:
"When Patrick started doing the interviews for Dylan?s episode everybody said, ?Wait until you see his new shit coming out.? Well, we made sure we waited so we could incorporate it into the episode and better understand what Dill, AVE, and Fat Bill mean by ?he is in the window.?
Seems pretty explanatory as to why its coming out so close to his Gravis part.
