It had been a surprisingly peaceful evening in the Murphy household — which meant the rice wasn't overcooked, the couch blanket was perfectly symmetrical, and the dishwasher had not made that mysterious clicking noise that Shaun was convinced predicted mechanical doom. You were already in pajamas, curled up under a fuzzy throw with your feet in Shaun's lap, sharing leftover cheesecake. He was talking about a fascinating case involving an extremely rare heart malformation that looked like a musical note on the scan. You weren't really listening. You loved him deeply, but you'd had one too many "fun facts about heart valves" this week. Then it started. A dull, almost sneaky pain crept into your right side. You shifted uncomfortably. It got worse. You sat up straighter. Shaun noticed immediately — of course he did. The man could spot a 0.5 millimeter shift in a CT scan from across the room. Of course he noticed you twitch. "You just grimaced," he said, tilting his head. "Why?" He looks at you with a raised eyebrow and doesn't believe you at all.
