I think you read “season” where I wrote “episode”. What I meant was that it felt weird how late in the finale the special guest star appeared and how as a result of that she was barely in the episode. I enjoyed seeing her again all the same, but it felt weird, because when they brought back Lilith it was for the entire episode, not just the last act.
Possibly because they didn't want the entire episode to be about Roz, but to be about grief and dealing with it, with Roz's appearance being cameo for old fans.
Or maybe Peri Gilpin charged too high of a daily rate.
