It's what happens when you get stabbed, get infected, get healed, don't tell him that you were possibly gonna die in the first place (because he was there for the stabbing and it's kinda hard to hide a chest wound) and he finds out.
And you fall off the wagon because shit sucks. And have a harder time getting off the wagon.
And then he finds out that you've not been taking your psych meds. And pitches a completely reasonable fit 'cause it looks to him like you're doing absolutely everything in your power to passively end it all and really, it's kind of the truth.
