Also, is there rhyme or reason to whether you call the Potions Master Severus or Snape? I understand that it would be Snape in Harry's POV, but in Severus's POV you seem to usually use Snape as well, except for the occasional Severus like the one at the beginning of the above quotation. I hadn't noticed it through the rest of the story in particular, but I think it was around this section that it caught my attention, maybe because there was a Snape and a Severus so close together. . . Not really sure.
