[So whoever did this was either incredibly fast, incredibly quiet, or not above playing dirty. Possibly all three. That doesn't give Erwin much hope for battling them, but at least they have a better idea of what they're dealing with.]

That's why I keep telling you to sleep in beds.

[It's a shitty, old joke, but it's the best Erwin can do at the moment. Now that he's not carrying Levi anymore, the muscles in his stump and shoulder are screaming, and Erwin doesn't know if he'll be able to carry him gently any longer.]

I'm going to have to carry you the rest of the way over my shoulder. It's going to hurt like hell, but it will get us out of here faster. Can you handle that, soldier?

[Erwin knows how Levi responds to orders, when they come from him, and he's not above using that to his advantage today.]
