The first image, which show the Sophie, is come from the martin twitter, idk that he deleted now, but is here.

The second image, which show the Jack's missing poster, the image appears on the trailer for the season B of the series.

The last image, which show Rosemary smiling for something, with trees on the background, and Rosemary is looking for down.

The temperature and the ambience, made think of the this 3 images are the one scene, beside, front from Sophie, have a thing that likes wooden post, and the second image has a Jack's poster in wooden post.

The funny thing, behind from Sophie, is the "Bon", for me, this is one more thing that makes me think about "Bon" be Jack.

For me, this images are from the 5 episode, because the 5 episode has name "Faces of the grief", something that, and this is probably says that is a episode about the Walten family dealing with end of edd and molly, and dealing with disappeared of Jack Walten, I think which will even have a scene with Felix talking to Jack and Rose about what happened with Edd and Molly... who knows right?

Have too this image of show Sophie and Jack post with she, that image appears on the episode 4, in beginning on the glitch, I think this image is a concept fron the scene, or reference, idk. But the her suit is the same, so is a young Sophie.
