So far, my favorite episodes of S13 have been
My favorite return from the dead
My favorite new recurring character
My favorite one-shot character (keeping in mind that anyone who's only been in one episode this season is a one-shot character, and if you happen to know they're coming back later, please leave me blissfully unspoiled)
Most regrettable death so far this season
Most puzzling retcon so far this season
My favorite candidate for Big Bad this season, out of the candidates we've been given so far
Favorite mid-season cliffhanger
Best choice of 'The Road So Far' music for the montage at the beginning of the first episode of a season
What are your feelings on how the brothers have been treated by the writers so far?
