All of the folks in the last panel have appeared previously; Nevus is on the cast page, and Mimsy the Gnoll has been with him all day. Mulch the Trog appeared way back here, when I was still trying to figure out what Trogs actually looked like. Spatchcock the Eyebolt was in this same office when Sylvester and Rosemary visited. And Frag the Gnoll has appeared a couple of times as well, but.. honestly.. it's not important enough to dig out a link.
