Raph felt like he was sucker punched in the gut; his face paled, and he stared into the unknown. His heart was beating fast, but everything was in slow motion. His body weight like paper, crashing on the pavement below him.

He blinked, realizing someone has caught him. His eyesight was still adjusting, but in that second, he realized he had some sort of panic attack.

"I-I'm fine." He stuttered, out of breath, not even knowing what anyone was saying around him. It was just rushed whispers all around him as he placed his feet on the ground, catching his breath.

"You're not fine if you just out right collapsed on the floor." He looked at Leo hauling him up, his brow lifted in surprise.

"I—what?" Hearing it from one of his brothers threw him off, the news of his dead brother even more so.

"Dude, you almost full on fell on the ground if Leo didn't catch you," Mikey was crouched down fanning at him, so he stood up tall, worry displayed on his face. "You sure you okay? I haven't seen you do that in years." He rubbed the back of his neck, dryly, Raph wasn't one to open his feelings.

"I said I'm fine." He said bitterly, Leo released him once he sustained his footing. He looked at Renet, fully forgetting she was there for a split second.

Despite that, he still had questions and wanted answers; "who murdered him?" He didn't care for the worry looks that his brothers were giving him; right now, though lightheaded, it wasn't about him. They may be eleven years too late, but it's better than not knowing their whole lives.

"It was the Shredder," she breathed, like words would hurt him, "I came 'cause the Shredder took over your city, which isn't supposed to happen, but now," she paused, thinking, "now I think I know what's going on."

"That doesn't make sense," Leo furrowed his brows in thought, "we haven't met Shredder until last year, no one knew we existed until then, how…?"

"He time traveled, but that's the one thing I can't figure out, only my Master and I have the power of time, heck, I'm still learning. I don't know how he had access to time travel." She shook her head, it felt like too much for her. Like bricks came tumbling down, and pinning her but she couldn't think about how her friends are feeling.

To think, their whole lives that their bro has died in some freak accident only to discover it was some enemy going back in time. But Renet couldn't figure out how he got the tech to do something so… out of his league. Her friends told her about Shredder so many times, but she never thought she would have to deal with him herself.

"For your whole future trip maybe, we should take a rain check," Mikey said, scratching the back of his head.

"Yeah, I was thinking we should go to the past instead; I think if we fix the mess Shredder made, it will fix the future too."

"Are you saying that Shredder killing Donnie changed the future?" Leo asked Renet, he may not know his brother, but for one brother to be down which led Shredder to take over New York was a little overboard.

"Yes," Renet replied quickly, "I mean, I'm sure if this happened to one of you guys it would have the same affect. But, Donnie's useful to you guys."

"Useful?" Raph asked, eyes squinting in thought. "No offense, but we live fine without him. Is this all necessary?"

"Unless you want to be Shredder's next victim, then yes." The sorcerer raised her voice, "he's your brother and my friend. I need to make this right even if you don't."

"I do." Raph shook his head, "I just… can't believe... this."

"I want to fix this, too." Mikey piped in, "I mean it'll be cool to have our brother back, four evens us out for once." He said to lighten the mood a bit, but he was being serious about them being back to four; they usually separated into one another or they stayed as a team and never split up. It depended on Leo's and Splinter's mood.

"Me too," Leo rested his hand on Mikey's shoulder, giving it a squeeze, "Shredder ruined our lives without us even realizing it, we have to stop him. Who knows what else he plans to do with this new trick of his."

Everyone looked at Raph, the turtle sighed loudly, "Shredder needs to be taken down and I will do anything to have him dead." He directed a look to Renet, "so what are you waiting for? Let's go."
