This says he left the book when he graduated. Isn't it possible that he took it with him, then when he returned as Potions Master that he brought it back, and then left it in the Potions classroom when he was given the Dark Arts job? --JKochRavenclawcrest(Owl Me!) 02:06, July 25, 2010 (UTC)

Either way's possible. Who knows? But according to Harry in the last chapter of the sixth book, Snape left it behind in the cupboard. So even if Harry mistakes Snape's treatment with the book, we should keep it as it is until proven otherwise. Yatanogarasu 02:37, July 25, 2010 (UTC)

The improvements that Snape made in this book are said to be incredibly useful, seeing as how Harry finished his potion faster than incredibly gifted Hermione. So... Why didn't Snape inform... I don't know, somebody, about these improvements? If they were really so good, wouldn't he be paid a fair sum, or maybe get his name mentioned somewhere? I dunno, if you think about it Snape looks kind of stupid and greedy by keeping them to himself. --{{SUBST:User:DoomZero/sig}} 01:28, January 2, 2011 (UTC) P.S: Does anybody know how to fix my sig? I have no idea how to get rid of that.

Remember that some of the things he came up with in that book were rather evil. As Hermione said, he most likely didn't want to be associated with it. --JKochRavenclawcrest(Owl Me!) 03:26, January 2, 2011 (UTC)

There is something different from the "Severus Snape"'s page

This page said Snape brought along this book with him after he grauduated and became a death eater. And he placed it in the potion classroom when he returned to Hogwarts as Potion master.

But "Severus Snape"'s page said Snape left his book after he graduated.

Which one is true? @@"

Altered Draught Recipe

I watched Half-Blood Prince tonight and during "Draught of Living Death challenge" towards the end there is a page which crossed over number 12 for a number of ingredient and written 13. So maybe someone could check it and edit it? Sekobro (talk) 00:17, August 4, 2015 (UTC)
