The ONLY worthy Commissar in the cul-de-sac would be Kevin
Sarah's a SoB
Jimmy's a psyker (he has the headgear, and hey, the reason he's so afraid is he can read everyone's thoughts, that would shit anyone up)
Rolf is an Ecclesiarch (always talking about the past, after all)
Ed- Ork, I'm sorry but there's no debate here, green jacket, (iz best!) focus on violence, he might even be a Mad Dok with his science experiment consisting of a fish with two chicken drumsticks sewn into the eyeballs.
Edd- Techpriest, ya.
Eddy's Brother: The Emperor, he gets mentioned a fair but but never shows his face.
As for Eddy himself...I'd say Eddie would be Commissar Ciaphas Cain, think about it.
-Always hitting on Naz
-Only cares about himself to the detriment of everyone else
-Always coming up with schemes
-Despite all of the above, is seldom punished for it and is well-known throughout the cul-de-sac (imperium)
HOLY SHIT GUYS, EDDIE IS CAIN!
