But my main point is that if the final Cylon is to be one of these minor or dead characters, we need to see more development and foreshadowing of them first. Zak essentially had not even been talked about for a very long time. Jospeh also was not talked about much until Baltar’s trial, but now of course he will get tons of development in the Caprica prequel, and very importantly it is revealed that he was… well, it’s possibly a big spoiler so I won’t say here for now. But I am not sure Caprica would air before the final one is revealed, so that may not have a bearing.
