This is an expansion of the forum thread, link, listing all the significant characters on the mostra and a brief descrizione of what we know about them as of the most recente episode. This means that this is chock-full of spoilers, and should not be read da anyone who hasn't seen all the episodes o doesn't want to find out about character developments outside of the pacing of the mostra itself.
