DesiredStorm, your guess was the closest. Read this to find out what it is.

As Raimundo stepped toward me, I grabbed a fist full of sand, and hurled it into his face. When his hands flew up to his eyes, I ran up to him and kicked his legs out from underneath him. He fell flat on his back. I raised my foot to knock him unconscious, when he threw sand in my eyes. It surprised me and I lost my balance and fell to the fell to the ground. The next thing I knew, Raimundo was on top of me, and his hands closed around my throat. They tightened for a moment, then loosed. I saw the angry expression on his face had been replaced with a horrified, confused one. I knew this reminded him of what his dad did to him and I knew that as much as he wanted to kill me now, he would not sink to his dad's level.

He scrambled up off of me, ran over to where the tiger claws were, and picked them up. Then I saw Omi and Clay were running towards him. Raimundo used the tiger claws to fly so they couldn't reach him, made a portal in the sky, and went through it. He was gone.

Omi and Clay ran to me, looking terrified.

"Are you alright?" Omi cried, looking at the bruises on my neck from where Raimundo's fingers were.

"Was that a mirage or did Ri really try to kill you?" Clay exclaimed. "He's either completely lost it or that thing on his head might be controlling him,"

"He's being controlled alright, but not by that thing," Dojo clicked his tongue thoughtfully. "Although it does control what's controlling him,"

Recovering after what had happened, I asked "Dojo, do you know what that thing was?"

"It'll be easier to explain when we get back to the temple. Right now, would you care to explain why he tried to kill you and then ran, because I'm not sure that the thing on his head would've made him do that,"

I wasn't sure whether or not I should tell them, but it didn't matter because something dawned on Omi at that moment.

"Kimiko," he said slowly. "Did Raimundo or Wuya by any chance use the thought keeper?"

I hesitated, then sighed, and nodded. "Raimundo did."

"Uh-huh," Dojo tugged on his chin. "Did you by any chance see anything he probably didn't want you to see?"

I sighed and nodded again. "But it had nothing to do with the fate of the world, or the temple, or us or anything like that. It was just some personal stuff. I don't really want to talk about it,"

They all nodded. I was glad that they understood. Then Clay turned to Dojo and asked "So what was that thing under Raimundo's hood? It looked more painful then a spur digging into your neck,"

"Like I said, it'll be easier to explain at the temple, so let's get going!"

When we were back at the temple, Dojo got out the scroll and laid it out in front of us. "Wuya must've found that before it was activated or I would have sensed it. It's a shen-gong-wu called the headpiece of wrath. It's used as a last resort because it's just a nightmare to wear, and extremely painful and difficult to take off,"

I rolled my eyes. "No kidding,"

"But what does it do?" Omi asked.

"Well, did you notice the red stuff coming out of the places the needles were? That wasn't blood, just so you know he isn't being hurt physically. Mentally though, it depends. See, the red stuff was anger. The headpiece of wrath makes you think about two things, and two things only. Who or what you're angry at, and why. That's all you can focus on and if somehow your anger starts ebbing away, the needles shoot more of it into you. That's probably why Raimundo was hurting while we were trying to talk to him. Not that I've ever tried it. Maybe the only reason he's with Wuya is to get back at us and if Wuya knows that's the main reason he's with her, she'd want to make sure that she wouldn't lose it. Right now, all he cares about is getting back at everyone he's angry at, and he doesn't care if he has to put the world in ten thousand years of darkness to do it,"

"Why would Raimundo put on the headpiece in the first place though? Would he want to stay angry so badly?" Omi wondered aloud.

"Maybe he didn't know what the headpiece would do to him!" I exclaimed. "Maybe Wuya told him it would make him invincible or something!"

Clay nodded. "That makes sense,"

He looked at Dojo. "So, how do we get it off?"

Dojo looked surprised. "Off?"

"Yeah," I nod my head in agreement. "How do we get the headpiece off so we can get Ri back to normal?"

Then Dojo's expression changed to mournful. "There's only one way. We have to kill him,"

That's it for now. I'll update soon. Bye!
