There's a moment of complete silence, and then he hears it: "Where do babies come from?" Levi promptly chokes on his tea. "I…what?" He waits a beat. Then two, then three. She stares at him, as if truly expecting an answer. "...You've got to be shitting me." Prompt: Levi struggles giving Mikasa the talk, and Mikasa is amused.
