See, that's a language Wash speaks, and he leans into it a bit. He puts on a grin and some very fake cheer. "I'm here to make sure you start your day on the right side of the bed." The grin and the cheer drop, and he shrugs, leaving that joke alone for the actual reason he's here: "Also, you're holding my cat."

...okay, so it's adjacent to the actual reason he's here. Good enough.
