Voldemort gasped as he returned to his normal state of being. He clutched his head, which was still pounding with pain almost as fast as his heart was. He suddenly started to throw all the books from the shelves on the floor. Books flew on every piece of the old oak wood flooring and Nagini just sit in her masters armchair; watching her master scream words she couldn't comprehend with, throwing books all over the place and watching pieces of paper fly over the room.
She lay still and finally Tom crashed on the floor, crying, throwing the last book onto the messy pile he made. He didn't understand. He didn't want to understand. He didn't want to feel anything he felt. Furious, depressed, sad, torn and most of all guilt and confusion. He was furious that Albus let this happen to Harry. He's always known that Albus was evil, that's why he wanted him dead. Not because he feared the man, heavens no. It was because the man manipulated him into trusting him, to treating him like a father and then crushing everything and blaming everything he did on him. Though he had to admit that the man was genius. Using Toms childhood thievery background to make everyone think he was pure evil. He was furious with himself for just making Harry's life more miserable by 'trying to kill him' even though he knew he was under the Imperius Curse (courtesy of your headmaster of Hogwarts). He was depressed because he knew that he couldn't help the boy there and then. That he was miles away from Harry when it happened. He was sad because all he could do was watch those innocent emerald green eyes cry. Why did he have to look towards him? Didn't he know it was harder to listen to his screams without him looking at him? He had felt confusion because he didn't know why his connection guard wasn't up. Confused because he was crying for a boy he didn't know; for all he knew this happened all around the world. And he felt guilty because he knew there was nothing he could do about it.
Tom couldn't do absolutely anything about the situation. Nobody trusted him. His Death Eaters were gone because Dumbledore managed to find them all and put them under him control (which after he found out he had killed many of them and then went on a muggle-killing-rampage). The only Death Eater he had left was Severus and Lucius and he thanked Merlin he had them at least. He felt guilty that somewhere, the Potter boy was crying because of what just happened. Somewhere, the Potter boy was hurting, his flesh burning. He was feeling the agony he was because neither of them had put up their guards and Tom absolutely was refusing to do so anymore. Not with what just happened.
He sat their, silently, and let a few more tears fall and then he silently looked at the floor. Drowning himself in his and Potters pain. Nagini looked up at her master once she felt her master had calmed down and hissed softly 'Massster what painssss you?' She tried as hard as she could to be comforting. She slithered over to her master and nuzzled his chin 'Whatsss wrong Masssster?'
Tom sighed. He forgot about Nagini completely. He pet her silky, scaly skin and looked at her with his deep red eyes. This proved to Nagini that her master was in pain. She had never seen his eyes such a dark red. Such pain and suffering in them.
'Nagini itsss the boy.' Tom mumbled, his head looking at the ground.
Massster I don't undersssstand.'
'The Pottersss boy Nagini sssweet. Remember? We used to go ssssee them. They had a baby boy, rememberssssss?'
'Yesss.' Nagini paused and nuzzled her masters chin, trying to make him look at her. When he did she continued 'Isss he in painsss? Isss that why massster is ssssuffering ssso?'
'Yesss.' Tom looked at her and gently stroked her. 'I don't wantsss to talk about it Nagi. Sssso go to sssleep. We will think about it latersss. Promissse.'
Tom looked at Nagini and gently smiled, trying hard to make her feel better. He knew that it worried her to see him like this. She wasn't used to it and nor did Tom want her to get used to it. He kissed Nagini on the head and stroked her again before getting up and heading towards the door. He whispered a 'Good Nightsss Nagi.' And went to his room to try to sleep. But Nagini still sat their, thinking about what she had just witnessed.
'Nobodyss makesss my Masster cry. Nobodysss.' And with that she made her decision. She would wait a week to see what her master feels like. She would watch him day and night and if she saw him cry again, she would seek out the thing that made her master cry so. She would get her revenge.
