Buck and Eddie get into an accident (perhaps on their roadtrip home) and Eddie gets badly injured. And like Buck does gets hurt too, but no where near as bad, so while Eddie is in the hospital Buck has to be the one to tell Chris. And it's just bringing back up all the memories of the shooting. Except this time it's worse cuz Eddie is an even more critical condition (maybe he's the one in a coma this time).
So Buck tells Chris, and he's expecting him to be upset obviously but he's always been so brave about these things in the past, so Buck doesn't think it'll be any more difficult than one would generally expect. Except, Chris has just been going through it this past year already, everything that happened with him running away to Texas, and then Bobby died, then Abuela, now possibly his dad.
And it's just a fucking breaking point for him and he flips the fuck out. He starts crying but he doesn't even notice it cuz he's too busy shouting and screaming at Buck. And he doesn't even know what he's saying he's just so fucking scared and he's had enough of trying to act like he's okay cuz he really really isn't.
Buck let's him shout at him, let's him hit him, it really fucking hurts, even tho he's just a kid, cuz he is still somewhat injured. It doesn't hurt more than Chris's words though. It's fucking heart breaking and Buck doesn't know what to do to make it better.
The cherry on top of the pile of dog shit is Chris saying he wishes it was Buck who was at risk of dying instead.
Now obviously he doesn't mean it, he just wanted someone else to hurt as much he was. And later when he's calmed down, Chris massively regrets it because of course Buck was already hurting as much as he was. He lost Bobby and Abuela too. He cares about Eddie as much as Chris does. He was hurting and Chris made it worse instead of hurting with him, like Buck was trying to do. He also knows he would've reacted just as bad if it had been Buck in the hospital so it was stupid to say anyway, and so of course he does eventually apologise profusely.
(Oh and Buck never tells Eddie about any of it)
