@gartender you'll hear it in Japanese, and of course when you directly translate it into English. In English you'd probably actually hear "Your lovely wife will make it for you!" instead.
Her face on the last panel isn't really flustered, because I assume she knows he's delirious. It's more concerned if I'm being honest, which is the reaction I'd expect because I don't think she would know how to react.
