Well, here is Part 2, as promised.

In this part, there is some medical stuff. I do try to do research on all medical conditions in my fics, but since I'm not a doctor or an expert, it's likely there will be mistakes, especially in regard to treatments, so I beg forgiveness in advance for my ignorance.

Thanks to my reviewers and my readers. :D

DISCLAIMER: I don't own TMNT. :'(

"Mikey! Raph! Mikey!"

"Maybe they're not here. Maybe they managed to find somewhere to shelter until the storm was over?"

"Maybe, Donny, but we've gotta check every inch of this park first, just in case."

"I know, Leo. I just - wait, what's that?"

"Where, Don?"

"Over there, by that big tree."

"I dunno, let's go check it out." The two turtles ran towards the large tree, hearts pounding, each of them both hoping and dreading they would find their brothers there.

"Oh no!" Leo was first to reach their target, and what he saw made his heart sink. Donny came up behind him and gasped. For there before them, were their missing brothers. Mikey was inside the hollow in the trunk of the tree, and Raph was partly outside it. The red-masked turtle was holding the orange-masked one in his arms, and both had their eyes closed and were motionless.

Jerking out of their shock, Leo and Donny immediately got to work. They knew their first priority was to get both of them into the warm, so Leo carefully pried Raph's arms apart, so that Donny could take Mikey. Leo then picked Raph up in his arms, despite his younger brother's large bulk, and both hurried towards where the Battle Shell was parked. A few minutes later, they reached the van.

Master Splinter quickly opened the back doors, so Mikey and Raph could be deposited inside. Donny climbed in too, while Leo went to get into the driver's seat.

As Leo started the van and set off home, Donny tended to his brothers, while Master Splinter looked on in concern, and did what little he could to help.

The heating in the Battle Shell had already been turned up to maximum, but Donny knew that wasn't enough. He piled blankets over the two inert turtles, and placed several hot water bottles around them, ensuring they were between the blankets and not touching their skin at all. Back at the Lair, they could use electric heated blankets, and some halogen heaters, but for now this would have to do.

He then went to check their vital signs. Neither appeared to have a pulse, but Donny knew this wasn't uncommon with patients suffering from severe hypothermia. Raph's breathing was shallow, so he fitted him with an oxygen mask. Mikey, however, did not appear to be breathing, which was also not uncommon in cases of severe hypothermia, so Donny immediately started CPR.

Suddenly Leo braked the van hard, and alerted them,

"We're here, let's move fast!"

Master Splinter went ahead, to try to prepare the infirmary somewhat before they arrived. Donny once again carried Mikey, while Leo took Raph. They were thankful for the elevator from the garage - getting their brothers down a manhole safely would have been very tricky.

Racing into the infirmary, the two turtles were carefully laid onto the beds, and once again covered with a multitude of blankets.

"Leo, I need you to do CPR on Mikey, while I hook them both up to the monitors, okay?"

Leo obeyed, as Donny set about connecting the multitude of wires to his brothers. As the monitors powered up, the one connected to Raph began to bleep intermittently, the line showing a shallow and slow pulse rate.

Mikey's, however, was one long bleeeeeep, with a static straight line running across the centre of the screen. Donny took over CPR, attempting to revive his youngest brother, while Leo and Master Splinter watched from the sidelines, feeling helpless. After a couple of minutes, he looked at the monitor and stopped the compressions. He pressed a button on the machine, and the continuous bleep was silenced.

"Don, what the shell are you doing?! You can't be giving up?!"

"It's no use, Leo. He's gone. He was probably gone before we even got there – we were too late." Donny's voice was quiet, and thick with as yet unshed tears.

"No! This can't be happening! You've got to try again! Haven't we got one of those electric shock machines they use on television? Just do something!"

Donny just shook his head sadly, staring hard at the floor.

"Well I am not going to give up yet!" roared Leo, although knowing in his heart that Donny's words were true. He attempted to continue CPR himself, until he felt a furry paw on his shoulder. He stopped, but did not look at either his sensei or his purple-masked brother.

Suddenly, Raph's monitor began to sound an urgent alarm. Donny jumped at the sound, knowing he had to temporarily brush aside his sadness if he were to save his other brother.

"Leo, come over here, quickly!" But Leo did not respond, he had a glazed expression, as he stared at his baby brother's face. "Leo!" When there was still no response, Donny rushed up to Leo and slapped him hard across the face. Leo stared at Donny, eyes wide with shock.

"Look, Leo, I know you're upset, well so am I! But if we don't do something right now, we are going to lose Raph too. And I don't know about you, but I would rather not lose another brother!"

This seemed to get through to Leo. "What do you want me to do?"

"His body temperature has dropped below 32C – we need to heat him up fast. I'm going to try to warm him up internally via fluids, but I'll need to go heat them up first. Leo, I need you to keep a close eye on him. At this point, there is still a danger he could stop breathing at any moment. If this happens, I need you to start CPR straight away, just like you did with M-… just like you did before, okay?"

Leo just nodded, to show he understood. Donny took a saline bag from the medical freezer, added some glucose, and was about to head off to the kitchen, when Leo stopped him with a desperate plea,

"Donny, he is going to be alright, isn't he?"

The purple-masked turtle desperately wanted to say 'yes', but at this point he knew it would be a lie, because he honestly didn't know. Instead, he replied softly,

"I hope so, Leo. I hope so." Then he swiftly exited the room, to heat the saline.

Minutes later, Donny returned with the now warm bag of saline solution.

"How is he?"

"I thought I lost him a couple of minutes ago, but I did CPR like you said, and he's okay now."

"Well done, Leo. Hopefully once I put this IV line in, the warm saline will help warm his body from the inside."

Once the IV was in place, and the saline and glucose was gently flowing into Raph's bloodstream, Leo broke the awkward silence by asking,

"What do we do now, Don?"

"We wait," was the simple response. But Leo could not simply sit around, waiting to see if his brother lived or died, especially not with Mikey still lying just a few feet away. He looked towards his sensei, who had been silent and still all this time.

"Sensei, what should we do with –" He could not finish the question, could not bring himself to speak the youngest turtle's name. After a long pause, Master Splinter finally responded,

"We cannot leave him in here. Leonardo, help me move your brother. Besides, when Raphael awakens, I fear the harm it will do him should he see Michelangelo like this."

"Of course, sensei." And with that, Leo and Master Splinter took Mikey from the room to lay him out, leaving Donatello alone in the infirmary.

He had not taken his eyes off the monitor screen, but it was not what was on the screen that he saw. Instead, all he could think about was Mikey, and all he could see was Mikey's face before him. Mikey's once smiling, happy face, now so serious and still. And Raph's life still hung in the balance.

He couldn't believe all this was happening – surely it must be some nightmare induced by too much caffeine before bed, and he would wake up any moment to hear Raph and Mikey having a fight over some trivial matter. But as time wore on, Donny realised this was not a dream, it was all horribly real.

Suddenly, the monitor gave out a small blip. Donny breathed a sigh of relief as he realised that Raph's core temperature was at last going up. He went to his brother's side, and reached under the heap of blankets to grab Raph's hand.

"Come back to us, Raph, please come back."

Part 3 is coming very soon (right now, I'm not 100% sure if there will be a Part 4 or not)

As always, reviews are very much appreciated, so please just drop me a line, even if its an anonymous review, or just one word. :D
