As they entered the reptile section everyone's eyes went wide at the vicious creatures that were snapping in random intervals. Yukio seems so docile though? Rin thought but continued to drag him along anyway. If this is what would entertain Yukio, or at least get a reaction from him, he wasn't going to ask questions.

"Nii san, it's really not that big of a deal." The demon completely ignored him as he continued to drag him along.

Rin stopped suddenly examining the different exhibits, looking for one thing in particular.

"Um... Rin,"

"Huh?!" He turned around angrily toward the voice, and Shiemi flinched a bit.

"Uh... I just wanted to let you know that we're gonna go look at other things for a while... that's

all."

He calmed down a bit and looked at the rest of them who also looked uncomfortable with the

tense air Rin was giving off.

"Fine."

"So you'll be he-"

"Yes. We'll be here."

Yukio turned towards them to get a word out but was yanked forward once again by his too-

strong older brother.

Izumo raised an odd brow at their behavior and Shima just laughed, commenting that it was cute.

Rin was being quite possessive and louder than usual. Finally the other exorcists were out of sight and Rin continued to search for what they had come for.

"Nii san... really it's-"

"Shhh!"

He gripped Yukio's wrist tighter. He's so determined to please me even though he knows it won't get that much of a rise out of me. He's too kind... makes me jealous...

Rin's face twisted in thought before he shouted at the top of his lungs, "Found it!" causing all the other people to turn and stare. Oh god. Yukio covered his face with his hand as he was forcibly lead to the snake pit exhibit. Rin stood there for awhile and then gestured for Yukio to get a closer look. Rin felt accomplished at Yukio's awed expression, which he tried to hide. He never told me he liked snakes? Rin laughed to himself. Why is he so kind to someone who isn't recibrical with these interactions...makes me jealous...

"Having fun Yukio?"

The thirteen year old Yukio silently slipped out of bed at the sound of his alarm clock, which he quickly shut off, for fear of waking his brother. He peeked over at Rin to see messy black-blue hair sticking up every which way and heard loud obnoxious snoring.

He slowly got out of bed, reaching for his glasses, silently getting dressed and stepping around things that would make noise. Right when he was about to leave the room, he heard the sluggish voice of his brother.

"Yukio..." He flinched.

"Yes, Nii san?" he whispered back. It was obvious Rin was still half asleep.

"Where you goin'?"

"Huh? Oh... Nowhere. Just... out for a bit."

"It's so early though?" He heard Rin yawn.

"I'll be back. Alright?"

He saw Rin turn over and smile a little in his sleep.

"Okay." He fell dead silent.

Yukio tensed and waited for the snoring to start back up again and it did. He sighed in relief and opened his bottom desk drawer to take out two small black guns and put them in his back pockets, covering them with his large sweater and exiting the room.

He knows Rin probably doesn't remember the exchange from that morning at all and it was sickening for some reason. That was the first time Rin had actually woken up when Yukio would get up early for exorcist training. That was the first and last time, that one time. His cover was almost blown. He'd been lying to Rin almost his whole life, over the biggest secret in the world but he couldn't even think of one, little white lie? Nii san...

Five words to describe Rin, huh?; Innocent, determined, protective, kind, open-minded... The list went on. And it made Yukio sick.

Rin leaned over the railing more to get a better look. Yukio's eyes were glued anywhere but the snakes. He stared as Rin leaned over, holding onto the railing for leverage.

makes me jealous...

He looked at his brother again. Rin was just having the time of his life the whole day, chatting with everyone, even Izumo, being loud and fun as usual... He glared at his twin's side though the demon was completely oblivious to this.

"Wahh?!"

Rin fell over the edge of the railing. Yukio smirked. Then he heard footsteps and his smile fell.

All he heard then was Bon shouting in confusion as he ran around frantically. He heard Shiemi

scream.

What have I done?
