I am considering this reasonably big news because this as far as I know is the first time we are seeing a full colour image from a Book 2 episode. This image is from Bryan on Tumblr and is from a colour correction session. So it is as close to a finished image from the show that we have seen.
Thoughts on what is going on ?, What is with the fence, and the fire ? in the background.
In terms of the Book 2 release date, hopefully the Nick Upfront event on February 26th will reveal it, because that is where we got the Book 1 date from.
