This is canon. Roy would absolutely do this if it would make the right people uncomfortable or if you paid him $5.

And yes, that is EXACTLY what the alt text reads. I just want to make sure there’s no doubt–this is a super canon thing that Roy would do for as little as $5 or the mere promise of making Frankie Morris uncomfortable. (Frankie Morris threw the party in chapter 1, knocked up Gracie, and can be seen in the background of this comic looking at beer.)
