Great job! It's chilling how Voldemort sees Snape as a sort of reincarnation of himself, and at the same time seems to be playing with him, or consider him some kind of child still. It certainly goes a long way towards explaining how Voldemort managed to miss Snape working against him right under his nose for so long -he thinks he knows Snape, because he knows himself. And the idea of Voldemort having some kind of rivalry with the Malfoys over Snape is delicious ;)
