Oh, this has been wonderful reading! I really adore the image of Neville and Harry man- (or plant-)handling Severus back into his pot. Their little asides to each other during the whole process were so dazzlingly funny!
The description of the plant was so suggestive that I'm surprised Severus wasn't more embarrassed by it.
I was enthralled by your mature, efficient Neville, and Severus' grudging approval of him.
