Thanks to my cousin for the generous lending of several minifigs; the new hair on Plummer is courtesy of him. More to follow...
Billy? Who the heck is Billy?
I think those Dwarves best be getting their hides outta there before they end up on someone's wall as trophy decorations! ;)
Observation: Plummer is about to bring a world of hurt to someone. Conclusion: This is getting good!
Billy's the dude with the fire extinguisher. He's been in the strip since the first panel. Granted, he's not been a focal character since the '08 Advent cycle finished, but he's been around - most recently as part of the ambush team that attacked Steve Vert-Sang.
