In a previous episode Booth fought to get a chair from a fellow agent that passed that was an older brown leather chair. In this episode we see a standard black office chair. It could be assumed that it was replaced as Booth had made comments that it was uncomfortable.
Towards the end of the episode, Seeley Booth asks his brother to go outside. As Seeley is leaving the bar, you can see he is wearing silver tennis shoes with laces. But once he steps onto the sidewalk he is wearing brown shoes.
When Jared kisses Brennan, he remarks that Seeley probably never had the the nerve to do that. However, the flashbacks in Episode 5:16 reveal that Seeley did dare to kiss Brennan, but she pushed him away.
Booth's brother Jared is wearing a naval officer uniform for Lieutenant Commander, and has stated that he is a Lieutenant Commander. He is holding his cap under his arm when talking with Bones. His cap has "scrambled eggs" (the gold braid on the visor of the cap) on it that is only worn by the rank of full Commander or higher.
