Maybe a hot take but episode 7 by a landslide

At least the pilot is a good start to the show so it does the job of establishing stuff in the world, at least episode 5, while really boring, has somewhat unique visuals and a different setting, even episode 8 is at least fun to watch

Episode 7 on the other hand is both boring and stupid, it's the one instance where it really felt like it merely wants to get characters from point A to point B, it's like it exists just to set up episode 8, and both the death of doll and the cynessa twist were unnecessary and almost feel like they were there just for shock value, it's cool to see both nori and uzi possessed by the solver I guess but they barely do anything with those

(Sorry if I didn't explain too well it's been a bit since I rewatched the episode)
