Hi, just decided to join a community. I love Severus Snape. Anywho, I am posing a question for all Slytherins. In the book, Order of the Phoenix, Snape tell Umbridge he has been teaching for 14 years. If that is true, and my math correct, does that mean he's been teaching at Hogwarts for two years as a Death Eater? I'm just a bit curious, but it never hurts to ask.
