Digby watches Louie die. We see that when Robby walks out he's been watching the whole time. I mean, from his point of view it probably looks like a whole lot of chaos, but he watches the staff try. Watches them fail. Watches how they all become a little more defeated by the situation because more than just a patient who died, it was someone they knew and liked, just like it was someone he knew and liked.
And I note this because it puts his support of them when the other patient is crashing in a slightly different light because he's watched it go wrong. And you know what? If they need space, he's going to give them that space to work. Just like he's going to congratulate them when they do good. He's not just impressed with them because he's a chill, happy guy.
He's giving them the props they don't tend to get for their work after watching how hard they take it when that same effort isn't enough.
