At first, he thought maybe his light meditation technique, which included envisioning Raph's warm body wrapped around him, was working fairly well. But a few moments later, his senses began to return, and he realized he was feeling warmth in certain areas because someone was carrying him. Carrying him rather quickly he surmised at the amount of jostling he was experiencing.

He breathed in and huffed out Raphael's name when the emerald turtle's scent filled his nose.

Raphael stopped in his tracks. He was carrying Leo on his shell and he wasn't at all certain that he hadn't just imagined Leo breathing his name out against the back of his neck. Finally, Leo said it again and Raph took two big steps backwards in order to press Leo's own shell against the sewer wall. Then turned quickly to catch him since he knew Leo wouldn't be able to stand up on his own two feet.

"Jackass," Raphael growled before quickly covering Leo's mouth with his own.

Leo's brain had been trying to fuzzily remember what had happened, but all thoughts disappeared when Raph pressed his body and his mouth up against him. He was frustrated when his arms wouldn't cooperate and follow his brain's command to reach up and grab hold of Raph's arms, but contented himself with the fact that his lips were moving enough to satisfy the both of them.

Raph pulled his mouth away so that he could rest his forehead against Leo's for a moment. Leo was breathing hard and was still alarmingly cold. As much as Raph wanted some more time alone with him, he knew he'd better keep moving quickly to get the frozen turtle back to Dr. Donnie. He didn't say anything further as he turned, easily pulled Leo back up on his shell, and continued his sprint towards the lair.

Leo didn't say anything either. Instead, he did his best to ignore how painfully numb his legs were and let himself nuzzle his face into the side of Raph's warm neck as Raph ran.

Raph sped up as the lair's entrance came into view and he spotted Mikey nervously pacing by the turnstiles.

"They're here, D!" Mikey called out as he raced into the lab.

Raph quickly followed and let Donnie and Mikey pull Leo gently off his shell and place him on the cot Donnie had set up. Master Splinter and April were standing by and quickly covered Leo with heated blankets, while Mikey adjusted the heat lamps they'd already placed around the cot. Raph also noted that it looked like every single space heater they owned had been pulled into the lab and were currently raising the room temperature.

Donnie was pleased to see Leo's eyes open, even if Leo's confused expression had Donnie worried about his mental status. He pulled Leo's mask off his face and then made a disgruntled noise as he ran a thermometer across Leo's forehead. When he was finished, Mikey quickly moved in and covered Leo's head in one of their warm winter hats.

"Hold still, Leo," Donnie said as he pulled one of Leo's arms out from under the blanket. He quickly stripped Leo's arm of its gear and then set to work inserting an IV with the saline they'd heated.

Leo thought about telling Donnie that he didn't have any control over his frozen limbs anyway, but didn't want to worry his clearly stressed family any further. So instead he kept his eyes locked on Raphael. Raph looked like hell, and was currently busying himself with reaching under Leo's blanket to pull his soaking wet, frozen gear off the rest of his limbs. Every once in a while he'd glance up and meet Leo's eyes, before quickly going back to his task.

Donnie had the IV inserted before finally looking around the room for his other patient.

"Where's Casey and Karai?"

The frantic note in Donnie's voice had Leo's eyes moving away from Raph and over to Don's worried face.

"They're comin," Raph grunted. With all of Leo's gear off, he pulled a stool up on the other side of the cot and found Leo's hands under the blanket with his own. "I made sure they made it out of the building before I took off. Casey couldn't keep up while helping Karai move and she refused to be carried." He turned then to their father who had moved to stand next to him. "I'm sorry I didn't wait for them, sensei."

Master Splinter rested a hand on his shoulder and shook his head. "You did the right thing, Raphael. Leonardo's condition warranted you returning here as quickly as possible."

Raphael looked back to Leo then and found that Leo's eyes were once again closed. He squeezed Leo's fingers hard and watched as Leo's eyes slowly reopened and locked onto his.

"Stay awake," Raph growled softly to him, doing his best to keep his voice from carrying to the others in the room.

They sat staring at each other while the others began to debate on whether they should run out to the tunnels on foot or in a vehicle to try to find Casey and Karai and bring them home faster. Mikey and April were about to leave when Casey finally skated into the room with Karai doing her best to hang onto his back using her stiff limbs, a compromise they had made when walking was proving to be tortuously slow-going.

Master Splinter felt another wave of relief as he watched April usher Karai behind a curtain set up in the room. Once back there, April quickly began pulling Karai's wet clothes off of her. Karai thought about arguing about the help, but she knew the redhead well enough by now to know how stubborn she was, so she'd probably just get an eye roll and a lecture about not letting Casey carry her sooner. Plus, April was bribing her with warm, cotton sweats to change into. So she did her best to look only slightly disgruntled as the other girl first undressed and then redressed her before moving her again to be set up on her own cot near Leo and the space heaters.

Karai examined Leo closely, as April stuffed her feet into warm, fuzzy socks. Leo still appeared to be a funny color, which was a strange thought because who would've thought she'd ever have their distinctive green colors memorized, but at least he was awake now.

In the next moment her father was there, covering her in heated blankets, before he checked her temperature.

"Your temperature is slightly low, but not as low as we had feared," Master Splinter murmured.

"I wasn't in the water that long," Karai said, slowly. "Leo managed to keep me out of it"

"We know," Master Splinter said, placing a winter hat over her head as well. "Donatello had surveillance in the building. It was how we knew you were in danger. What were you doing in there?"

"Oh, Karai, here," Casey said, digging into his hockey bag. He pulled out the photo album she'd insisted they fetch before they left.

Karai offered him a real smile as she took the book from him. Then she turned to his father. "I wanted this," she said, turning the book over to him.

He sat down on the edge of her cot and slowly opened the album she and Leo had risked their lives for. His eyes immediately moved over pictures of Tang Shen. Pictures he hadn't seen in years.

Mikey moved in close and looked over his shoulder. They'd seen Tang Shen in the formal family photo Master Splinter had in the dojo, but these pictures were completely different. These photos showed Tang Shen with her hair down, swinging on a swing, laughing at the camera.

"She's like, totally young there," Mikey said in awe.

Master Splinter only nodded.

"There really wasn't anything else I wanted in that tower, but I couldn't bear the thought of these photos being lost," Karai said, watching her father's face. His expression was stoic and she was having a hard time deciding if he was pleased to see the pictures or not.

"Hold still, you're bleeding," Donnie suddenly said, pressing gauze against Casey's neck. "What happened?"

Donnie's frantic voice once again pulled Leo's attention to him and he looked across the room in time to watch Donnie force Casey down into a chair. He took in Donnie's wide, worried eyes as they examined Casey's bleeding neck.

"One of those razor-covered balls of doom," Casey said, nonchalantly, doing his best to play off the injury, at least until he got a look at Donnie's face.

Leo watched Casey reach up and grab hold of one of Donnie's busy hands, forcing Donnie to meet his eyes.

"Couple stitches from you and maybe some of that special Dr. D beside manner later," Casey said, softly with a wink. "I'm gonna be fine."

Leo suddenly felt like he was watching something private between the two, but couldn't pull his eyes away as he watched Donnie visibly relax under Casey's soft, reassuring words.

"And hey, maybe I'll get a gnarly scar out of the deal," Casey called out as Donnie moved away to collect what he'd need to stitch him up.

Leo turned back to Raphael and found Raph's green eyes still watching him closely.

"I'm sorry," he whispered out to Raphael and watched as Raph quickly shook his head and squeezed his fingers again.
