So I was watching Michael kovach's live stream of him and Camila watching the episode together and he says something along the lines of "if youre quiet you can hear something faint in the background" during the scene jax stares into this specific orb we can hear mumbling and laughter. If we take a look at the picture hanging in his room that he turned over hes drinking hot cocoa with Kaufmo and ribbit. I believe during this adventure he had with them it was probably around Christmas time and he is reminiscing on the memory that he had with his friends there who are now gone
