He wasn't sure what happened. One minute they were fighting a bunch of foot guys, Hun, and trying to find a way out of their situation. The next, he heard Rayn shout, a bunch of explosions, and suddenly the walls on half the room were coming down on them.

"Guys? Are you okay?" Mikey called out from somewhere in the aftermath.

"I'm good." Donnie replied, using his bo-staff to get himself off the ground.

"Never better." Raph called out from somewhere to Don's left.

All three waited for Leo and Rayn to call out, but emptiness fell across the room.

"Rayn? Leo?" Don shouted across the room. Still, neither answered.

Exchanging an uneasy glance with Mikey from across the room, Don started to look around for them.

Soon the other two joined him, and together they combed through the remains of the warehouse. But none of them found anything.

"Don." Raph called out softly, holding up something.

"Rayn's backpack." Don realized, recognizing the color. He easily caught the bag as Raph tossed it gently in his direction, carefully unzipping the main pocket. Rayn's robot was still intact, somehow, after the room almost fell down on it.

"Where do you think they are?" Mikey asked, worry clouding his features.

Distantly, they heard Rayn's scream, followed by more silence.

"Rayn! Leo!" Raphael yelled, racing over to where he heard the screaming, his brothers on his heels.

"They must be trapped behind this wall of debris." Don realized. The room had been divided by a large pile of debris, separating half the room.

"Is there another way around?" Mikey poked through the debris with a hand, yelping as some of it fell towards him.

"Probably, but we have to hurry. The explosions caused the structure of this place to weaken greatly, so it's likely to fall down at any moment." Donatello spotted a door to his right and pointed. "Come on, this way."

All three raced towards the door. As he exited, Raph briefly considered the lack of foot ninja in the room with them after the walls collapsed. Must've got scared off, he mused to himself.

Rayn and Leo were shoved roughly into the back of a unmarked van, tied to the seat, and left alone. The rest of the ninja - and Hun, probably - must have took some other means of transport, because there was no way they'd all cram into the front of this thing.

The doors were slammed shut and they were left in almost darkness. It had to have been past 4am by now, which means the sun would come up soon. Hopefully.

Absently, Rayn turned to Leo. Guilt laced her insides; she had dragged him and his family into her own mess, and she didn't want anyone to get hurt because of her.

"Leo." She whispered. "You need to find a way out."

"I know, Rayn. I don't know how I'm going to get us out." The turtle frowned, his face heavily shadowed in the van.

"No, I mean you have to get out." She looked at her hands. "Leave me, this is my fight. I don't want you to get hurt because of it."

Leo looked up at her sharply, but her face was a steel mask that he couldn't read. "Rayn, you're family now. We're not about to let anything happen to you." He said softly.

A small window opened up to show a face in the front of the van. It was apparently Hun.

How the heck did he even fit in that front seat? He was huge, that shouldn't be logically possib—

Rayn's thoughts were interrupted sharply by his voice.

"Alright girly, say goodnight to your little green friend. You won't be seeing each other for a while." Hun laughed, shutting the door. Rayn exchanged a look with Leo.

"What is he..?"

Then a sickly green gas started filling the tiny van, making her cough and lean over the seat.

"Sleeping gas." Leo choked out in realization.

"Leo.." Rayn, nearly doubled over in her seat, fought the weariness wildly. "Keep.. close. It's the .. Only way." She coughed out. "They need to… keep us together."

Then she slumped in her seat, clearly having succumbed to the gas.

What is she talking about? Leo asked himself, as he felt his own vision grow darker. How am I supposed to do that?

His last sight before the world went dark was the door opening and a man watching them as they passed out.

"Come on, pick up." April huffed, holding her shell cell to her ear. She had tried both Leo and Rayn; neither answered. Now she tried Don.

The phone kept ringing and ringing.

"That's it, I'm going in." Casey growled, opening the door to the Battle Shell.

"Casey, wait." April put a hand on his shoulder. "We need to be here for them if they need us."

"Fine." Casey sat back in his seat, watching the smoke from the warehouse intently. "They have 5 minutes."

Inside the warehouse, Don had led Raph and Mikey to where he thought the other side of the rubble was.

They had to leap over a half-collapsed wall in the hallway, but they found the other entrance to the room.

"There's..no one here." Mikey glanced around briefly.

Don frowned. He was right. They must've escaped, or..

"Were they taken?" Raph finished Don's thought for him. "Why, that big ol'.."

"Do you think they're..?"Mikey asked the unspoken question.

"We don't know that for sure, to either of those things. For all we know they're just waiting for our rescue somewhere. Come on." Don led the way into the room, observing every inch closely.

The three fanned out, wary of the damaged walls and collapsing building. They didn't have long to look, so they moved and covered ground quick.

It only took them a few minutes to return back to the entrance, looking defeated. "I didn't find anything." Raph growled. "They must've been captured."

Don frowned, surveying the area yet again. Something was bugging him - knowing Leo, he'd surely put up a fight if they were surrounded. Something must have stopped him—

"Wait!" Mikey shouted, kneeling and pointing at something. "Look!"

He pointed towards a bracelet, half covered by fallen rubble. It was very simple, made of some kind of metal, and had a small part of it that almost looked like a watch.

"Mikey, wait—" Don called out as he realized what it was. But it was a second too late, Mikey had already reached to pick it up.

Instantly, the turtle jerked his hand back as if he'd been burned. Raph raced over to inspect it, instantly worried though he tried to hide it. "Mikey?" the hothead called out.

"It.. Zapped me!" Mikey yelped, holding his hand. Raphael reached out a hand and Mikey took it with his other hand, letting his brother pull him to his feet.

"It's Rayn's." Don whispered, reaching over and picking it up easily despite Raph and Mikey almost reaching to stop him.

"Why can you touch it?" Mikey complained. "Wait, isn't that the thing she had on in the lab before? And said it'd zap anyone who tries to touch it?"

"Yeah." Donnie frowned, deeply troubled. He recalled a conversation he had with Rayn a few days back.

Rayn was sitting at her desk, sitting at his computer when he entered the lab. Her bracelet and robot were strangely connected together with some sort of wires, and all of it was connected to his computer.

"Rayn, what are ya working on?" Don called out as he entered.

Rayn jumped, stifling a scream, and sighed as she spotted Don. "Don, don't do that. You guys and your ninja-sneak ups are going to give me a panic attack." She complained, having almost dropped her robot.

He held up both hands in apology, walking over. "Sorry."

Rayn sighed, looking troubled. "Don, I need to ask a favor." She whispered, her face changing to look entirely serious. "I want to sync my robot to your aura, so that if I ever get captured, it won't fall into the wrong hands." She held up a hand before he could interrupt with a question. "It's synced to mine right now, in the event of my capture, I can enter a code and hand the controls to you. That way, you could keep it out of Wylan's or Hun's or whomever's hands. And maybe even use it to find me. Will you let me?"

Frowning slightly, Don gave a single nod. "Of course." He answered almost immediately. "We're like family now, anyway." He said softly, briefly hiding his face to cover a blush.

She nodded, not noticing. "Thank you."

"Just tell me what I need to do and how to work it."

"Rayn.. Told me a few days ago she wanted to transfer the robot's controls to me in case she was captured." Don explained after a moment, not realizing Raph and Mikey were waiting for him. "She and Leo must have, because that's exactly what she did."

All three exchanged worried glances, as they heard a rumbling of the building's supports above them.
