I was so distracted in this episode by Richard Ayoade's voice as Zero and also trying to figure out who played the female Twi'lek that I completely missed that it was Clancy Brown playng the Devaronian until I saw his name in the end credits. Then I went back to his introduction scene and kicked myself for not recognizing his voice right away.
Couple that with Bill Burr and Mark Boone Junior and this episode was way too chock full of recognizable guest stars. It kinda took me out of it.
I also had to roll my eyes at the third (at least) use in this series of the "weapon goes off but it's not the person we think getting shot" trope. IG-11 in the first episode, then the sniper assassin in the krill episode, then Zero here. Did I miss any? Mix it up a bit, people!
