Sasuke tapped his chin. A week had passed since Naruto left to Germany, and since then, Sasuke's been trying to figure out how to settle whatever the idiot had scribbled on the piece of paper.

"Hey there."

Sasuke cringed at the obnoxious tone as he slid the slip of paper into his pants pocket, "hey Karin."

"So how've you been? I haven't seen you in weeks."

"Yeah, okay. Since Naruto left, it's been rough." He scratched the back of his neck.

"Heh, I'm coping pretty well without the idiot." Karin rolled her eyes.

"Tell me about it..." Sasuke chucked, "listen, I need to talk to you about... This."

"Uh-huh?"

"I just can't anymore... I'm sorry."

"That's fine."

"What?" Sasuke was a little disappointed the twenty dollars he spent on self-defense from Obito didn't pay off, "really?"

"I've been pretty out of it lately, ever since Hidan was killed." Karin shrugged, "and, uh, I've been seeing someone else."

"Really? What a coincidence!" Sasuke chuckled awkwardly, "so thanks for taking it better than I thought you would."

"It's okay, anything for you, Sasuke!" Karin grinned, "you know Suigetsu?"

"The weird white-haired kid?"

"Yeah, that's him..."

"Really?!"

"Yeah, he's got a sense of humor you lack." She laughed, "okay, well, bye Sasuke! It was a lovely relationship, but, they never last forever, do they?"

"Not... Really..." Sasuke replied weakly as Karin walked off.

"'What a coincidence'?! Pfft, clearly you've never broken up with someone before..."

Sasuke rolled his eyes, "oh please, that's coming from someone who's been with two boyfriends already."

"Hey, I only broke up with one of them."

"Uh-huh, same difference." Sasuke wrapped his arms around Sakura and hugged her. When he let her go, he stepped back and sat on the park bench just near them, "look."

"What's this?"

"It's the paper Naruto gave me when we saw him last."

Sakura peered at the chicken scratches and rose a brow, "this is Naruto's hand-writing?"

"I mean, it came from him, didn't it?"

She shook her head, "nuh-uh. This is far from his writing."

"Then whose..." Sasuke tilted it in different angles, "hold on... Could this be..."

"He's been in jail and juvy so many times, they have his own cell just for him. Well isn't he special?"

Sasuke rose a brow as he overheard Obito's and Itachi's conversations.

"I also overheard..." Obito continued, "he's the leader of his own little group in the prison. He's practically a regular. Once when I was spying on their group after Kakuzu got out of jail, he came up to Hidan and told him 'hey, you left your papers in the cell again'." Obito laughed at his artificial impersonation of Kakuzu, "I mean can you imagine? Hidan is so forgetful, he leaves his shit all over the cell like that!"

"This is Hidan's."

"How can you be so sure?"

"I remember overhearing from Obito that Hidan's forgetful-ass brain tends to leave his trash in his cell. Naruto must've picked this up." Sasuke looked back down at the paper.

"Well..." Sakura crossed her arms, "that explains the messy handwriting, that's for sure. Now the hard part is decrypting it..."

"It's not that hard..." Sasuke rolled his eyes, "it looks like some sort of barcode number." He pulled out his phone and typed in the number into the search bar. He hit 'search' and they waited until a large variety of results popped up.

"Huh, it looks like it's a product he was buying..."

"And it's..."

Sasuke scrolled through until Sakura stopped his finger, "hold on..." She pointed to a link, "what's that?"

He tapped the link and it sent them to a shopping site, "so what? It just looks like some hardware store or something."

"No, look at the product he bought." Sakura pointed to the title, "it's a propane tank."

"Propane..." Sasuke muttered, "hold on... Back in the warehouse..."

"There was a propane tank, releasing propane into the atmosphere." Sakura thought back to what the forensic experts told her that day, "Propane is an asphyxiant gas, used in suffocation."

"This is our evidence we can use against Hidan, and clear Naruto's and Itachi's name!" Sasuke stood up, "come on, we need to get to the station now!"

"Okay, okay! I'll drive." The two of them ran to her car and headed as fast as they could to the station. When they got there, they parked, but Sakura didn't move to get out.

"What's wrong?"

"He's in Germany..." Sakura realized, "it won't make a difference whether he gets out or not, he can't come back if he can't afford a plane ticket. And he's only seventeen, how'll he get a job to earn that money?"

Sasuke pursed his lips, "damnit... We can talk about that once we get things with Naruto and Itachi straightened out."

"Right. Okay." Sakura nodded, and they got out and headed inside.
