Drastic measures on the battlefield are one thing, Erwin. If your husband is just a call away to come get you, that's another.

Why talking to Jean would help with puking up flower petals, Levi can't begin to puzzle out in the moment, and just assumes maybe Erwin's getting delirious as well.

He's got the kettle going and tea measured out (herbal, with a little honey), and goes to retrieve one of his face coverings from the cupboard. "How's Jean?" Presumably not dead or turned into a plant.
