I finally watched the 1st episode - Daryl & Carol are always so good on the screen together.  I felt they could have leaned more into Julian's "only human left theme" in contrast to them.  Daryl & Carol have always had people but their instinct is often flight, withdraw or disappear. Survival = running.  Julian was the opposite.  Alone for so long, his whole motivation was connection.  Survival = reaching out.  What is the correct balance between those two things?  A line from Julian saying "I'd rather die reaching out to people than live running away from them" Only to have Julian die & Carol disappear would have tied things up neatly.  Maybe it's too on the nose, idk. 

A ruined London was pretty cool/awful to see.
