Sweet. Just submitted the CS, making some minor edits to fix some fucked BBCode tags. What I usually do when a vital role isn't filled is I just NPC them without making a character sheet up - that way if they turn out to be on camera enough that they need one I can sorta make up key traits on the fly, and if they don't then they stay in the background where they belong relative to the PCs. Plus it saves the effort of thinking of everything in advance.
