Ahahahaha! I was dying laughing from the minute Harry was all, "Oh, yeah, this? It's just a potion Poppy gave me for the pregnancy...yeah, that's all..." Way to go Harry, lol. That was probably the best payback ever, though I was a little sad that Severus got so upset. :(
This was so good, lol! I loved how Severus just very casually threw back in Harry's face most of his attempts to thwart him, and jeez - never thought I'd see the day Dumbledore gave into bribery. But it worked! So great.
