I am totally up for a Fire Nation party! I hope the Mars kids will all attend. I know no matter what happens Lilith will show up to meet him in person finally.

Caterina would go to diplomatic reasons? This Fire Lord is a lot easier to chat with and they would make a useful ally in tracking down whatever remains of the Orden.

As for Claire, Jacob (and probably Bella too) will be all about saving her. How does Brian feel about scary insanely huge wolves appearing out of nowhere?
