I'm looking for a story. Its a Snape mentor story. I only remember this part where Harry was talking to HErmione in class one day and Snape thinks he's cheating gives him detention and in the detention Harry explains he can't see. So Snape asked how he can find a snitch and Harry tell him its cause the snitch is all shiny and moves but the letters on the board don't. OR something like that. Any idea what this is?
I'm not sure if this story is even findable, but I remember a Master-Apprentice fic involving lots of rules and such. Snape wasn't really for all the extra rules and power he had over his apprentice, but he REALLY worked Harry hard, I mean to the level where he was helping out as a teaching assistant? I remember that there was an addition of a PE class for Hogwarts, and a scene where Harry is doing pull-ups with his back exposed and there were bleeding whip marks. (Not given by Snape, but related to the apprenticeship thing) It was complete and something like 40 chapters long on FF.net, but for the life of me, I can't find it again! This is from several years ago, so can anyone help me find this? I think it had a really simple name, like Master's Apprentice, or something similar. Thanks for any help you can give!
