This post was inspired by one of the asks I got about a hope for a worried for Buck Eddie.
Eddie in 3x05 - After Shannon died, after the tsunami, Christopher had nightmares, and Buck nearly died 3 times and was unavailable to be there because of the lawsuit. Eddie was struggling to deal on his own. This is where we first find out just how dependent Eddie has become of Buck and vice versa. We see how apart the two drift and spiral.
Eddie in 5x14 - Explaining to Christopher that being scared and sad can be exhausting, but it's important to talk about it anyway.
Buck is there for all of it. That anchor, that unwavering presence, is what helps Eddie find the courage to do the work in order to get better and to open up to Christopher about the process.
This time, Eddie is scared and sad, but this time, he's not dealing with it alone.
There are a couple of references to the lawsuit's dark time in latest seasons. One is from s5b (☝️) and the second from in s6a (6x05) - both revolve around buddie moments, the one is connected to the fight, the other to the make up scene (3x06).
