What time find most interesting about this scene are all the trophies in the background. There really isn't any mention of them directly throughout the movie, so we can assume this is a way of telling us of how successful the family or a member or the family may be. I believe the most noticeable part of this scene is Royal Tenenbaum and how he is laying in the bed. This is one of the times we see him really vulnerable throughout the film and it is portrayed in the way he is laying in the bed.
According to this sequence you can tell who is closest and most comfortable with Royal. Richie and Royal's close friend are the closest to his bed. These are the two throughout the movie that really listen to Royal and sympathize with him. Next are his grandchildren, who just met Royal and don't have any hostility towards him. The next closest character is his wife who was willing to let him live in the house and talked with him without too much hostility. The furthest characters are his adopted daughter, and his son that is most angry and hostile towards him. This shows distance in the relationship and less closeness. This scene does move the composition forward because they all do show concern for their father while the doctor is there. Though there are some issues and bad relationships, they are all there to hear what the doctor has to say and if the father will be okay. The way this scene is set up does have a similar appearance to the last supper. They are all gathered around one main subject. That is interesting to consider when watching the rest of the movie.
