Hard choice for me this month. Every NPC that I interacted with was fantastic (like....my 6 children!).
But I think I am going to have to go with Abe (angry prisoner, my child who tried to climb over the guard rail, and Aezir Jr) and Sam (because, come on, Emperor Boris was fantastic).
I think everyone did amazing.
But must give mention to the PC-NPCs playing evil/resurrected versions of PCS
Sam - Boris
Brett - Garridan
Nichole - Iso'bel
Brooke - Ithada
Nick - Krow (you bastard)
