No. And I don't think Jonathan really interacted with Joyce either during this episode, which was odd.
Erica was delightful in small doses last season, but they used her so much here that she got irritating. She earned some points back, though, when she cut off Dustin's lovey-dovey exchange with Suzie. And I enjoyed the Neverending Story duet, but thought it went on too long and killed some of the momentum. It might've been worth it to see Hopper's reaction, though.
I liked Robin, but I think that by adding her and spending more time on Erica, they didn't give some of the returning characters enough to do. I particularly wanted to see more with Will since I thought his story this season started out so interesting, only for him to spend episode 4(?) on mostly just serving as an early warning system for the Mind Flayer.
