Hi! Glad you guys liked chapter 3! Well anyway, hopefully this chapter will be just as loved. You know, I had a different account…I posted a really bad fanfiction and a lot of people liked it….I wonder why. It had bad grammar errors….misspelled words…well I waited a while till I got better at writing…which I'm sure I did! Anyhow…I better stop rambling on…Sadly, I don't own Naruto or any of the characters used in the story. But on with the chapter! Enjoy! ^-^

Tobi woke up a couple hours after he fell asleep. The first thing he noticed was that the strange feeling from earlier had altered into something completely different. Anger. Gloom. Broken trust. A voice inside his head seemed to endlessly be whispering the same few sentences. Get rid of him. Kill him. He's a threat. He couldn't stand it. He may be angry at Deidara, but he wouldn't hurt him…would he? He lay in his bed for quite a while trying to drown out his thoughts before he finally fell back asleep.

He woke up to bright light flooding in through his window. Squinting to see he sat up and stretched. This morning he was in a surprisingly good mood. The feelings from earlier weren't as noticeable, and there wasn't anything telling him kill, hurt, or get rid of anyone. He stretched and reached for his mask that laid on the table next to is bed. It wasn't there. He looked on the ground….it wasn't there either. He checked under his bed…he still couldn't find it. By now he was getting a little agitated.

I don't have time for this, Thought Tobi as he checked for what seemed like the thousandth time under his bed. There was another mission today and he didn't have any extra time to look for his mask. If it wasn't in his room then where was it? Maybe he left it in the bathroom last night when he took a shower. He checked the time. It was still early no one else should be up yet. He slowly and quietly opened the door and looked both ways down the hall…it was deserted. He silently snuck down the hallway, careful not to wake anyone up. As he arrived at the bathroom door, he reached for the handle but stiffened to the sound of a door opening behind him. Deidara…

"Oh, you're already up. I was going to wake you. You do remember the mission we have right, un?"

Tobi nodded as he opened the door and looked around. His mask wasn't there.

"What are you looking for, un? Asked Deidara, as he watched Tobi search the bathroom.

"Nothing," said Tobi as he looked down at the ground so that you couldn't see his face and turned. He didn't want anyone to know he lost his mask.

"Well hurry up, I'll be downstairs, un."

Tobi looked up and watched Deidara leave. After he was gone, he began walking back to his room when he noticed something bright orange out of the corner of his eye. He quickly turned his head and sighed in relief, he had finally found his mask. But the smile quickly vanished when he noticed where it was. His mask was under the bed in Deidara's room. Why? He didn't know why…his best bet was that Deidara stole it. Because? He didn't know exactly why he stole it. Probably to piss him off. A million reasons and thoughts ran through his head, but whatever it was, it didn't matter…he was furious. Very furious.

He rushed into Deidara's room and grabbed his mask up off the floor. He wiped off the dust, put it on quickly, and stormed off down the hall. He walked quickly through base and into the kitchen where Deidara stood. Without hesitation, he walked forward towards Deidara and slammed him against the wall. His fingers tightly wrapped around his neck almost completely cutting off the air.

"What The Hell Was My Mask Doing In Your Room!?" His voice quite a bit deeper than before.

Deidara managed to choke out a quick reply, "I-I don't know, un. I didn't take it."

Tobi's grip tightened. "Liar. Just stay the hell away from my stuff."

Deidara hadn't lied. He didn't even touch it let alone take it. Why would do that? There was no reason to…besides maybe seeing his partners face, but he didn't care enough to actually try.

Tobi glared at him for a moment, though it couldn't be seen from behind the mask. He let go. Tobi turned his head to look at Kisame, who was sitting at the table watching him. Kisame looked away, and Tobi turned towards the other room.

"I'll be down in a minute. Be ready to leave."

Deidara stood there watching as Tobi left. Once he was sure Tobi was gone, he frowned.

"What just happened, un!?"

Deidara was confused. Tobi doesn't act like that. It's as if he is a completely different person. What happened to his overly cheerful, happy-go-lucky attitude? Though Deidara did find it rather annoying, he was starting to miss it.

Soon Tobi was downstairs again….they left without saying a word.

Fortunately the mission assigned to them was rather easy. It was completed in a couple hours, and they were back before lunch. They both had the rest of the day to do what they wanted. Deidara spent most of the day in his room. He mostly worked on unfinished clay sculptures. Tobi also spent most of his time in his room keeping to himself, and not wandering around the base annoying everyone. No one really noticed.

He sat on his bed trying to forget. That's what Tobi wanted to do. He wanted to forget what happened several days ago…the explosion. He wanted to forget the horrible dream he had when they returned from the mission…the dream he had when he hit his head and blacked out for a minute…the same dream he seems to have every night. He wanted to forget finding his mask in Deidara's room….he wanted to forget everything.

He can't forget. It's hard to do when a small voice in your head continuously reminds you...everyday getting louder and harder to ignore. The pain in his head he got the other night still happens every so often….but it's not as noticeable…it only lasts for a few seconds at a time….nothing to really complain about.

Tobi laid down on his bed and gazed up at the ceiling. He wasn't in a too terrible mood….he still couldn't figure out why he had gotten so mad at Deidara earlier. Of course it was his mask and it did irritate him that he took it then lied about it…but why so angry? He couldn't figure out why, or if it had anything to do with something telling him he shouldn't trust Deidara….or telling him to kill Deidara. He didn't know if he should listen to it or not. It didn't seem right.

He decided to stop thinking about it, and stood up. He hadn't had any breakfast or lunch…and it might be a good idea not to starve. He opened his door and headed down the hallway and down the stairs.

Deidara frowned. He couldn't seem to get the clay figure he making just right. He had been trying for quite a while and all he had done was make himself frustrated. Sighing, he set it down.

"Maybe I just need to take a break, un." He said to himself as he stood up.

He was going to go outside and go for a walk. He stepped out of his room and headed towards the stairs. He looked down at the ground as he tried to figure out what he was doing wrong with the clay, when suddenly he ran into someone.

"Watch were you're going, un" He said in an angry tone, as he looked up to see Tobi. He didn't know it was him…if he did he wouldn't have said anything. Aggravating him wasn't a great idea at the moment.

Deidara was expecting to get yelled at, or pushed to the side….but no. Tobi didn't say, or do anything but stand there for a moment then walk past him. It was a little odd, but Deidara didn't say anything.

Tobi walked down the hall and back to his room. He was trying to ignore his thoughts again.

Come on…don't you see how he's treating you? You deserve more respect…has ever really shown you any? No. Kill him…he's a threat….kill him.

When thinking back to everything that has happened…he realized his thoughts are right. Deidara really hasn't shown any respect towards him. Just thinking about Deidara makes him angry.

Tobi cringed as the familiar sharp pain ran through his head, but seconds later it was over. Without much more thought he silently made a decision…

Deidara…should die.

OKAY! This was chapter 4! Yes it's horrible….and short. I needed to update this! Hope it isn't too bad!
