I'm not worried. I was worried (and rightly so) when we learned that DS was coming back for 13 eps this season. Extremely worried!
Christopher is never going to cause trouble again, I think. Both Luke and Lorelai are now sure that Christopher is not an option. Chris might not be sure, but that's his problem LOL.

I might feel a bit anxious if we were told that DS signs for a full or half S8 and SP doesn't.. yes, that'd freak me out, but otherwise I'm calm. Totally

That said. I would LOVE a convo between Luke and Chris about Lorelai that the battle is over. Absolutely.
