Well, I have some questions in my mind which disturb me each time I read Harry Potter. Please take time out to answer!
1. In Harry Potter, it has been maintained that no evil witch/wizard has emerged from any House other than Slytherin. How is that possible when we all know that Peter Pettigrew (Wormtail) was a Gryffindor! Please don't reply by saying that no one knew of his true nature uptill the 5th book; because if that is so, then what about Sirius Black, who, until then was a convicted murderer?
2. Voldemort could not kill Harry because Lily died to save him. Voldemort could not kill anyone in the Hogwarts battle after Harry cast himself before Voldemore, trying to save all in Hogwarts. But then, why could Voldemort kill Lily? James too had died in order to save Lily and Harry, telling the former to take Harry and go! Was James' sacrifice not enough to evoke the magic?
3. Harry spotted Thestrals in the 5th book, while he saw Cedric die in the 4th. He should have been able to see those Thestrals on his way back to the Hogwarts Express, where the students are led by the Thestral-driven carriages. As a baby, Harry had also seen Lily die. So, he should have spotted Thestrals even earlier.
4. Harry's Invisibility Cloak (one of the Hallows) was said to be impenetrable to most curses and jinxes. But then, how could Dumbledore immobilise Harry at the top of the Astronomy Tower before he died (at that time, Harry was wearing the Cloak). Even Draco Malfoy was able to perform the body-bind curse (Petrificus Totalus), when Harry was sitting in the luggage rack of the compartment in Hogwarts Express, wearing the "impenetrable" Cloak!
I would be back with more questions after these questions get answered 😆
