>>118455399S2 had a lot going on for it: good cop/bad cop villains on the chase, chemistry between protagonists, existential train magic,
Jesse going back, and pretty much strings free fanfic-as-much-as-you-want ending.
Compare this to S3 where every episode past 2 is constant tension, breaking of relationships, hard lessons about empathy, and Simon's obtuseness. Simons end
of a surprise roach storm was particularly deus ex, and the season was much more uncomfortable to watch. It sets up for s4 Amelia/Grace with a Cat showdown, if s4 happens at all, and I personally think some character resurrection magic will occur.
