Episode 3 DOES NOT deserve as much hate as it is getting.
The audience saying "we want answers", you will get them. When it comes to writing TV shows you have to introduce things to finish plot lines.
Victor knowing the yellow man is HUGE which will contribute to providing those answers. Acosta looking through the stuff people left will provide answers. Jade knowing about the lake of tears and taking mushrooms will provide answers. The riddles from the boy in white to Tabitha and Henry will be figured out and in time, provide answers. Much more will happen with Sarah now being with Sophia and they framed the shot with both Victor and Sophia so perfectly as to allude to what is yet to happen.
Considering a lot of the audience is here after binging the episodes. You need to consider that there are 7 episodes left in the season.
Aside from plot I thought the cinematography and the editing in this episode was absolutely outstanding and among the best in the entire series.
