First of all, DON'T SAY THAT NAME! Second of all, it's obvious after reading the Deathly Hallows. This is why I don't get romance 22:00, October 14, 2010 (UTC)
(I didn't know this until I started editing the Wiki, the films depict them in their late 20s to early 30s.)
Doesn't that make Snape 21-22? And I'm sure Voldemort and Bellatrix were 'friends' in their school years, but Voldemort is at least 50 (Chamber of Secrets being opened 50 years before Harry's second year and Hagrid was in school and was a couple of years older than Tom) but Bellatrix looks a tad younger than the two...

Black family (+0)
...that Phineas Nigellus Black was the biological great-grandfather of both Walburga Black and her husband Orion?
This is not suprising. As Sirius Black said " The pure blood families are all inter-related. If you only let you children marry pure bloods your choice is very limited. There are hardly any of us left. Molly and I are cousins by marriage and Arthur is something like my second cousin once removed."
Willy Widdershins (+1)

Shows how Snape isn't a great DADA teacher 24.49.35.99 05:51, December 30, 2009 (UTC)
Maybe that`s why Dumbledore never made him a DADA teacher until Book 6.
...that Harry Potter only played in one Quidditch final, which was in his third year? Various circumstances prevented him from playing in the final match every other year.
Reason why I put this down for consideration is how aside from the COS, GOF, and DH is that even though Harry played in Quidditch matches that season he only played in the Quidditch final in POA, which ironically is also the only time he helped Gyriffindor win the Quidditch Cup, both of which I generally remind myself of since I noticed this fact after reading that book and figuring it out when comparing it to the other books. Therefore this is something only an experienced reader can figure out and should be noted since it is a noteworthy trend that affects that is present throughout the entire series. -Adv193 04:20, November 6, 2009 (UTC)
Of course! That's why in the 3rd book there was such mania in the Gryffindor team about winning the Cup. Everyone thought that they should have won it every year and each year something had gone wrong. Wood says in a training session "This is our last chance, my last chance to win the Cup. Ever since Harry's come on the team I'd thought it's been in the bag. But we haven't got it."

That's why the prophecy that is made could have applied to either Harry or Neville. They both had parents who had fought against Voldemort, they were both born at the end of July, etc. Although I guess we can quite easily forget it.

Hermione didn't used magic in front of a Muggle but with Wizards too...so that she never get in any trouble.--Giulliven10:53, February 13, 2010
Hermione wasn't outside of school while she used magic as she hadn't started at Hogwarts yet the rule is dat underage wizards aren't allowed 2 use magic outside school and if da ministry did find out they would think it was just a sign of her powers
Hermione probably didn't know about the rule because she didn't go to Hogwarts yet so the ministry might of just let it slide. —The preceding unsigned comment was added by 75.87.80.78 (talk • contribs).
She was probably around adult wizards and witches. The spell that makes it so they MoM can tell when an underage witch or wizard uses magic outside of school only detects magic, not the user. So, one could aruge that the Weasley kids could spend their entire summer doing magic around their parents and never get in trouble. However, this rule is more than likely inforced by parents. QueenSno 12:30, August 15, 2011 (UTC)
She also admitted to using magic at home around her Muggle parents,"Of course, I've only done a few simple spells, but they've all worked for me".

...that when Snape questioned Harry in his first ever potions lesson, he was really saying something else? "What would I get if I added powdered root of asphodel to an infusion of wormwood?"

So Bitter Yet So Sweet. The most beautiful and touching moment in literature that I have ever read. If Snape hadn't asked Voldemort to spare lily's life, then her death wouldn't have been a sacrafice. therefore, Harry would have died and there would be no Harry Potter. Snape is a hero. RIP.
