Quirrell may not have been casting the Killing Curse, but even so, Bellatrix cast it nonverbally in HBP to kill a fox, there is precedent that it can be used without speech.

Also, why didn't the Weasley twins EVER explore the 3rd floor corridor? I thought of the Trio asking them before, but I couldn't make it work. I can always use the excuse that they wanted to keep their mission a secret.

Also also, if Harry is invincible to Voldemort, why doesn't Dumbledore send him to fight in the front lines? An invincible kid is better than an adult any day.

Also Also Also, why does DD force HP to live with the Dursleys for the entire Summer, yet in later years he only has to spend a short time there?

Harry awoke in the hospital wing with Dumbledore by his bed. After knocking Quirrell unconscious, he had run back through the puzzle rooms as fast as he could. Halfway through he slammed into Dumbledore and McGonagall who were told of the situation by Ron and Hermione. He threw himself into Dumbledore's arms and started crying. He told Dumbledore the story on the way to Madam Pomfrey to make sure Harry was not hurt. The second Harry hit the hospital bed he fell fast asleep, and slept until halfway through the next day.

"Sir! What happened? I have the Stone!" Harry started patting his pockets to find it.

"I found the Stone in your pocket, Harry. I put it in the mirror, after all, so I knew you would have it. I charmed the mirror to give the stone only to someone who wanted to have it, but never to use it. Pretty good idea, if I say so myself."

"But the mirror, I saw my family in there."

"That is the Mirror of Erised, Harry. It shows you your heart's deepest desires. Many a man has starved himself to death by sitting in front of the mirror, so amazed by what they saw that they could not turn away."

Harry could understand this. He would have sat with his family until the end of time if he could.

"What do you see in the mirror, sir? Is the mirror broken?"

"I see the same as you see, Harry. I see myself surrounded by my family. You and I are a lot alike, Harry. And no, it would take much more than a topple to destroy the Mirror of Erised."

"What happened with Quirrell? And Voldemort?"

"Quirinius Quirrell is on his way to Azkaban. He may be there already, as a matter of fact. His trial will be open-and-shut, of course. I do believe he will be there for the rest of his life. As for Voldemort, he is gone once again, probably looking for another body to share. The entire school knows about your adventure in the forbidden corridor, Harry. They saw Quirinius being escorted from Hogwarts by Aurors, so they know he was involved. But you, Professor McGonagall and I are the only people who know what happened in that chamber. You may tell people what you like, but I must ask you not to mention Voldemort being involved. As we discussed before, I do not wish to have a riot when people learn Voldemort is still alive. I do not, however, expect you to keep this secret from your closest friends, as long as they too can be trusted with secrecy."

Harry agreed.

"Why couldn't Quirrell touch me, sir?"

"It is because of the sacrifice your mother made for you. It saved you from death once, and now under your blood relatives protection it will continue to guard you against Voldemort or his followers. I do not believe, however, that you would survive another killing curse, so I do not want you off trying to find Voldemort as if you were invincible.

"Harry, about this summer: I imagine you do not wish to spend it with the Dursleys, and as much as it pains me to say this, I am sure they do not wish to spend it with you either. When you leave Hogwarts, you must go to stay with them for a few weeks, at least, so you will still consider their house a home and still be under its protection. After that, if you wish, I may be able to arrange it so you can stay with the Weasleys for the rest of the summer."

Harry was overjoyed. A summer away from the Dursleys! He talked with Dumbledore a while longer, then he left.

Ron, Hermione and Hagrid also came to visit him in the hospital. As he considered them all his close friends, they all heard the story, and Ron said his parents would be thrilled to have Harry stay for the summer. The trio's adventure had earned enough points for Gryffindor to win the House Cup, of course; Harry expected nothing less after fighting Voldemort himself. At the end-of-year feast, Harry and his friends were approached by the Weasley twins.

"Harry! We could have told you to stay out of the forbidden corridor! You go in, widdle yourself and say your prayers when you see that dog because you know you're going to die, then 2 minutes later Snape shows up and gives you a month's detention. You only go in a door like that once!"

"Now they tell us!"

Soon the exam grades came. Harry and Ron both made better than average marks, due to studying with Hermione all year. She, of course, was top of the class in everything, except Herbology. Neville's Gran, who taught him Herbology, must have really been a star in the greenhouse, for he had made top of the class in that subject. It made up for the rest of the classes in which he barely scraped by.

When they arrived back at Platform 9 ¾, the old guard let them through the archway in small groups as not to cause a scene. Harry met Ron's parents. Dumbledore had already asked them if Harry could spend most of the summer at their house, and they obliged. Harry told them exactly how much better that would make his life.

Then, Harry turned and saw the Dursleys. It would be a long three weeks, but he had no choice but to go with them. At least they didn't know he wasn't allowed to perform magic...
