I've created pages for the new characters we've seen so far, but locked them just as a safeguard against spoilers (less trouble for me if someone goes on a spoiler spree :P). I also protected the pages for Part 3 and Part 4, so as to avoid cast spoilers for both of those parts. The new character pages should be unprotected by the end of the spoiler embargoes for Part 1 and Part 2.
Let me know if you have any questions, and I hope you're all enjoying the new series!
