Unsure, and I like the idea of the casting being either Prince John or King Richard. "Prince Marcus" seems to be a placeholder for the real role. Which could tie well into both a Robin Centric AND a Camelot episode.

I will throw a left field entry out there. From the list of forgotten plot lines, maybe this Prince Marcus is related to the Dragon Daddy for Lily, and could therefore be a setup for 6A. (I doubt we'll see Lily or Dragon Daddy in the finale, since Agnes B is close to having her baby.)
