I'm on my fifth rewatch and I've never been entirely able to put my finger on what's going on with Bos in S3E4. I'm curious what everyone thinks about two instances of how subdued or disenchanted Bos acts in two scenes in this episode.

The first is when he talks to Diane at the party he says he's lost his taste for all of it, despite seeming to enjoy himself before. Is it because he's done putting on a performance? Was it seeing Joe that tripped him up? Was it because Diane was talking about her ex husband and it brought up bad memories with his wife?

Later, I think I'm a little bit even more confused when Bos talks to Gordon. Gordon says he must like no longer being the big boss who is feared. Bos seems to take this personally, but why? Isn't that who he signed up to be when he decided to move to California at the end of season 2? He was disenchanted with the good ol' corporate boys. Why does this seem to sour Bos' mood to the point where everyone is asking him to play laser tag he gets angry? Was it because of the earlier conversation with Diane as well?
