snape and quirril

We all know Snape is very skilled at Legillimency and Occlumency. We know Snape always suspected Quirrel in the first book.
how come Snape could not use Ligillimency on Quirrell? He should be able to find out what he was up to.
The only thing I can think of is, that Voldemort prevented him from doing so. Voldemort is skilled at Occlumency and Ligillimency too, as we learned in OotP, so maybe he shut Quirrells mind and thoughts, but then doesnt that show that voldemort distrusted snape from the beginning and therefore why didnt he ever punish him?
Did Voldemort have the power to do so. Because the body and the sould are two different things, and so are the thoughts, it doesn't make sense. Voldemort shoulnd't be able to have the power to shut Quirrells mind, because it isn't his soul. Indeed, he shared Quirrells body, but surely he didn't share his sould and his thoughts?
And then, to my biggest question. If Voldemort really is so very skilled, and he must have heard Snape talking to his body-share, does he know Snape works for Dumbledore? Because IF Snape does, and he pretends to be a Death Eater, how come Voldemort didn't suspect anything? Because Snape and Quirrell DID have some chats. Voldemort should have heard, and understood. Snape probably did not suspect Quirrell to be walking around with Voldemort on the back of his head, so I don't think he was shutting his mind while talking to Quirrel, or maybe he was?
Still, the biggest question of them all remain. What about Voldemort finding out Snape's Secret? Does he know?

(I found this question on the web, but it really got me thinking)

err okay so mabey quirrle could blok his own mind i mean he was a professor so he couldent be all stupid and voldemnort proberly couldent here what they were talking about and quirrl didnt tell him.

For the first question, I think that Voldemort could easily had controlled Quirrel's mind. After all, Quirrel was not the most intelligent man and Voldemort is so powerful that it would have been easy, in my opinion anyway.

As for Voldemort hearring that Snape was on Dumbledore's side, he did know it. Snape mentionned the fact, in HBP, that the Dark Lord had forgiven him and trusted him when he talked to Bellatrix and Narcissa. So Voldemort knew that Snape worked at Hogwart, but that probably only gave him more chances to be forgiven, since Snape could bring so many informations to Voldemort. He had been close to Dumbledore and all that had happened all those years... in Voldemort's place, I would have forgiven him too to know all the things he could tell me about how ready and how strong the good side was, etc..

With quirrel having such a feeble mind, Voldemort controlled him easily. But with Snape, well Snape isn't a weak wizard and Voldemort knows that Snape is one of Dumbledore's most trusted people. That is why he is biding his time and preparing for his ultimate attack.

Snape is safe for the moment cuz he's working for Voldemort and also partly for Dumbledore. He's a double agent and I think Voldemort knows he can't take over Snape like he could Quirrel. Cuz Quirrel was realllly easy to control. Snape's very intelligent and can stop Voldemort from controlling his mind too.

As of right now, Voldemort pretty much loves Snape considering what he did to Dumbledore. So, any previous doubts he had about him might be gone. Might Volders isn't a complete dum dum.

So, as of right now, I think Snape is going to openly stick with Voldypoo, and be very undercover for the Order. Then at the last moment he saves the day lol.

Snape could be on either side at this point, though it IS possible that he may have plans of his own.

Well, if he does betray Voldemort-which he most likely will- then his death is going to be towards the end of the 7th book just before Harry and Voldemort have their final battle.

Yeah, as much as we all love Snape, I don't think he'll survive.

He's going to redeem himself for one side or the other, most likely the good guys.

I thik that Voldie was overtaking quirell's mind. With Quirell being so weak and Voldie being stornger, it should have been easy there for blocking Snape out of Quirell's mind.....

Well since we're back on this I'll say I agree :D

Poor Quirrell...he got so messed up.Speaking of him, how do we know if Quirrel died? The book said "left him to die" but did he? Is it possible Quirrel could come back?

Ginny, that is a scary and weird thing. But im thinking if he really is dead couldn't he be an infeti?

No, because Voldemort just left him there. So I'm thinking if he were to be an inferi he'd have to perform a certain spell, and Dumbledore wouldn't do that because that's Dark Magic.

If he does come back I think he might be slightly off, like Lockhart is. Of course, Lockhart was always off.

I think JK mentioned in an interview that Quirrel was officially dead. ~will look for that site again~

Quirrel was evil and when Harry touched him, he got seriously hurt, so I wouldn't doubt that he was dead because of the love that he and Voldemort at the back of his head had to endure...

I think Voldemort would have had no trouble controlling quirrel, but snape couldn't do legilimency because voldie was in quirrell's head and would have done his big occlumency against snape...

I do think that Voldy would kill Snape if he knew he was there. But thats it. I don't think he really wanted to kill snape because he was too weak. All he wanted to to was get his power back and kill Harry then he could worry about everything else. Including snape.

But I meant that at this time he didn't know about the wand and he would of killed snape because he thought he had turned to Dumbledore's side.

the reason Voldie never said anything to snape through quirrel because he wasn't sure if he'd become one of dumbledore's followers or not

Well he thought Snape was on Dumbledore's side. It would have been interesting if he did tell Snape because Snape was only out for himself and protecting Harry for Lily. He would have been in a very sticky situation
