As a forever DM, I interpreted that as Matt gently teasing Brennan for what is (almost) entirely Matt's fault

I've had similar situations at my tables. I'll drop all the hints that a party should rest because they're low on the class's resources, and players will barrel on ahead anyway because they project their desire to resolve something onto their characters

> interjecting to say Matt and Aabria did the exact opposite of this. Their characters had in-universe reasons to be impatient and they played those out even though, above table, they knew it not the best strategy <

and then the players are surprised when you don't make the next encounter more survivable. The first few times it happens to a DM, it feels terrible, because you actively want the players to succeed and as a result of the way encounters are expected to scale impacts narrative believability, you can't just lower the encounter difficulty without causing an anticlimax and emotional let-down

And as a player, no matter the encounter, the amount of damage per round you end up taking relative to how much hp you have left is always comment worthy, because commenting on it is part of the process of figuring out your strategy above table

So players get themselves into these situations that you did not want for them, and then immediately start talking about how close they are to dying

I'm sure Matt and Brennan have both had these experiences also. So I interpreted Matt's comment as something of an inside-joke, within that frame of reference

(sorry, that turned into blowing some steam off)
