Karai: Myra doesn't own TMNT, Nickelodeon does, otherwise this would be on TV every week instead of .

After dropping April, her father, and Casey off at they went back to the lair where Donnie promptly took Splinter into his lab to make sure he was alright. Splinter of course used his healing hands meditation to speed up the poison removal process but Donnie being more of a turtle of science still insisted on an anti-venom and prescribed some rest and meditation.

Karai brewed some tea for her father to take to his room and then the rat master decided to spend some time alone.

That left seven of them to fend for themselves for the time being. Donnie retreated to his lab again. Leo ended up watching a repeat of Space Heroes, Mikey half watched with him and half read a comic book. Aaliyah also stayed in the living room but she borrowed Donnie's laptop to cruise the internet for a while. Karai sat outside the dojo underneath the tree, partly for her own meditation and partly to keep an eye out if her father needed something.

That left Raph and Jennifer with some rare privacy time. The two of them only retreated to just outside the lair where for what constituted a date after Jennifer threw together a couple of ham sandwiches for them.

"You know, if this ever gets too weird you can always bail." Raph said to the blonde.

"You mean dating a mutant turtle or facing countless unknown threats?" Jennifer teased him with a smile and then placed her hand on his arm. "I'm not going anywhere by choice." She promised.

"You have no idea how much that means to me." Raph admitted quietly to her so that his brothers could not hear him even if they were trying to eavesdrop.

"It's okay. You have no idea what it means to be accepted into this family after my own fell apart so long ago." Jennifer replied. "I think in truth it's one thing we have in common, we both know what it means to find something we thought we should never have."

"Yeah. I guess you could say that." Raph agreed.

They ate in silence for a moment until Jennifer saw Raph flinch. "Is something wrong with the sandwich?" She asked concerned.

Raph shook his head. "No, it's not the food." He answered her. "It's…something else. I feel like…like something is drilling around my head."

"Want me to get you something?" She asked him.

At that point they heard Mikey complain loudly, "Dude, will someone please turn off the drill trying to smash apart my brain?"

The two of them got up. As Raph hopped the turnstile and commented, "I don't there's a brain in that skull of yours to smash apart." Jennifer had to contend herself with walking through the turnstile.

"It does feel kind of weird." Leo said. "I mean I hear some kind of drill sound too."

"My head feels almost like I'm having a migraine." Aaliyah added her observation. "I used to get them, some of them were so bad the only way I could get rid of it was to sleep it off."

"I'm going to check with Donnie and see if he feels it." Jennifer told them. "Because honestly I'm not feeling it."

They were all interrupted by a bellowing from Splinter's room. Karai was the first one to be on her feet and her tonta raised for combat. "Father?" She called out quietly. "Are you okay?" Everyone sans Donnie was now at the doorway too.

Splinter came out of his room with his hands over his ears. "It is too loud." He murmured. "Turn it off."

"Dude, The Marker's getting to him." Mikey whispered to Raph, who promptly smacked him upside the back of his head for the stupid comment.

"Father, what's wrong?" Karai tried again.

"You don't hear it either?" Leo asked his older sister.

The kunoichi looked over at him. "Hear what?" She asked.

"We haven't checked with Donnie yet but the others are hearing something akin to a drill in their heads." Jennifer explained to Karai. "But I don't hear it either. I wondered if it was something only mutants can hear, but you can't and you are one too."

"I haven't been one as long as they have." Karai reminded the blonde. "And it seems to be affecting father more than it does them anyway."

"That's because it's ultrasonic." Came Donnie's voice from behind them. "I had a sound wave monitor going just now and it caught it. I didn't know if it was a problem here until now." He started toward Splinter.

The rat master shook his head. "Cannot…concentrate. Feel…" He never finished as he let out another bellow and then got on all fours and started to run out of the dojo.

"Father!" Karai exclaimed but was not prepared for it and couldn't even try to catch him.

Donnie was directly in his path but was likewise not expecting it. Splinter ran right into his smartest son and Donnie sprawled backwards, tripping and landing on the couch. His hand flew against the table and Leo's water spilled all over the top of his head.

"Hah." Mikey laughed.

Leo and Karai were already trying to pursue their father as Raph glared at Mikey. "Can it Mikey." He looked to Donnie. "Pick up what's left of your pride and let's go." Jennifer was nicer as she helped the purple masked turtle to his feet so they could all go after Splinter.

"Father, please." Karai called out. "Slow down. Tell us what's going on."

Splinter ran into an open part of the sewers and the others started to follow but their chase was interrupted by several laser blasts.

"It is the one's known as the turtles and the one's known as their human allies." A Kraang stated. There were over a dozen others there too as if they had been set up.

One of the Kraang hesitated a moment. "When were there five creatures known as turtles in the one's known as the thorns in our dorsal regions?" One wondered.

"What do these bubble gum things want?" Karai asked. "We don't have time for this."

"No we don't." Leo agreed. "Karai, Jennifer. Go on ahead and find Master Splinter. The five of us will stay here and deal with the Kraang and we'll catch up with you."

"Is that such a good idea?" Donnie asked as he drew his bo staff. "What if there are more Kraang around?"

"Text April and Casey and have them meet you." Leo told Jennifer as he drew his katana's. "They can track you with their T-phones and the homing chip in yours."

"Be careful you two." Raph said as he drew his sais, but his gaze lasted longer on Jennifer and both girls knew who he was really trying to watch out for. Both girls also knew who really needed it more.

Mikey drew his nunchuck's and Aaliyah drew her bunrei's. The two girls ran off to try to pursue Splinter as Jennifer sent a quick text to their other two human friends.

"Kraang, eliminate the turtles." One of the Kraang droids declared. "They must not interfere in the plan that is known as the plan."

The five turtles started toward the Kraang droids to take them down so they could catch up with their sister and their blonde friend.

"Do we even know which direction Master Splinter is going?" Jennifer asked Karai as she was following the kunoichi's lead.

"I know which direction he's going." Karai answered her as she ran just a bit ahead of Jennifer since she had been trained to do stuff like this longer than the blonde. "I can smell him…Father kind of smells like prey to me."

"Is that bad?" Jennifer asked her softly.

"Not most of the time." Karai said. "Luckily. But sometimes I hate that feeling."

Two more Kraang droids came out from out of nowhere. Karai jumped up and used her tonta to chop the first Kraang droid nearly in half and turned to deal with the other one only to find Jennifer had her baton out, blade extended, as she placed one of them in the head of the Kraang droid and the other in chest before she flipped it onto the ground, defeated. The kunoichi's respect for Raph's blonde girlfriend went up another notch.

"This can't be a coincidence." Jennifer said. "I don't know why but I have a feeling that the Kraang want Master Splinter."

Karai nodded. "I have a bad feeling you're right." She agreed.

They girls went on for just a bit longer before getting sniped at by another two Kraang droids. Karai did her best to block with her tonta. "We have to get to them and get rid of them so we can move on." She stated.

"I know." Jennifer agreed. "But how?"

Karai was about to try a few shurikens but the need for that disappeared when a flash of steel whizzed by and disarmed both of the Kraang droids. They turned to see April coming from another direction as she caught her thrown tessen. Karai took that opportunity to guarantee the Kraang droids were out of the fight and none of them even paid attention when the two Kraang that had been inside disappeared.

"About time O'Neill." Karai joked wryly.

April shrugged as if she didn't really care what the kunoichi said but the tone of her voice indicated she got the joke. "I got turned around under main street." She said with a shrug. Then she changed the subject. "What's going on?"

"Father is acting weird." Karai said. "He's hearing something that seems to be…like, driving him crazy and the other turtles can hear it too like a drill in their heads."

"He ran off and we're trying to find him but the Kraang are getting in their way." Jennifer added. "That's where the other turtles are."

"I can feel him." April started as Karai interrupted with, "I can smell him."

"Who cares how we do it." Jennifer interrupted them gently but very firmly. "Let's just go after him."

More Kraang droids came around the very corner that the girls needed and started to blast at them but was interrupted by "Goongala!" as three hockey pucks with cherry bombs duct taped to them flew by them and destroyed the Kraang droids.

"Well what are we waiting for, let's go." Casey said as he skated up to them. "Before something happens to the rat dude."

Karai gave him kind of annoyed glare but left it alone as she followed her father's scent, the other three right behind her.

After a few more minutes of travel April said, "I recognize this place."

"What?" Karai asked.

"Me too." Casey said. "This seems like the tunnel toward the subway station where the Kraang were pulling the giant space worms into our world from Dimension X to milk them for mutagen."

April shuddered a bit at the thought.

"Oh ,right." Karai said. "That was happening when Tiger Claw first showed up to work for the Foot clan." She shot April a look that was hard to interpret. "That was when I overheard Father tell everyone who I was, despite some believe that I was an evil witch."

"So you heard that, huh?" April questioned and shrugged a little. "Sorry about that." She sounded sincere but she didn't seem embarrassed in the slightest. Truth be told Karai could not really blame her for that since at that point it was easy to see why the red head would have drawn that conclusion.

"Forget about it." Karai simply responded, being almost mysterious about rather or not she was sincere about it herself.

April and Casey were right though as they found themselves in the center of the station where at one point a giant portal had been set up for the Kraathatrogon to be brought onto Earth. Instead of the portal though was a bunch of equipment. On the table was an unconscious Splinter, who had either been knocked unconscious from a Kraang laser blast or passed out from the pain. There were also another three dozen or so Kraang droids.

"I still don't see what could have caused Splinter to freak out like that." Casey said.

"I don't either." Karai verified.

"I'd like to know what they're up to." Jennifer said. "Why are the Kraang…doing whatever they're doing to Master Splinter?"

"Looks like they're copying his memories." They heard from behind them and turned to see the five turtles approaching them, they had unsurprisingly made short work of the Kraang droids that had tried to ambush them first.

"You found us." Jennifer couldn't help but be delighted to see Raph so soon.

"You guys left a nice trail for us." Raph replied with a smile.

"And you'll be happy to know the one with the hole in the face and chest was done by none other than your girlfriend." Karai said to the red masked turtle, deciding she had to brag for Jennifer just a little since she didn't think the blonde would do so on her own.

Raph nodded approvingly. "Nice." He commented which made Jennifer blush.

"Hey, that device over there." Donnie interrupted them as he never the less put one arm around April in a hug, in which she briefly laid her head on his arm with a small smile, that Casey pointedly ignored so it didn't bug him too much. "According to my T-phone app the ultra-sonic wave is emitting for it."

"So we break it we help Splinter." Aaliyah surmised and then rubbed her forehead gently. "Not to mention get rid of our own damn headaches."

Donnie nodded sympathetically. "Exactly." He confirmed.

"Great, but to actually free sensei we're going to have to get past tons of Kraang droids." Mikey noted. "That's not so good."

"We don't have a choice." Leo reminded his youngest brother sternly.

Raph pulled out a shuriken. "I'll snipe that little device from here and then we turtles charge in." He said.

Leo nodded. "Good idea. Jennifer and April, get Master Splinter and try to get him home, Karai watch their backs. Casey, keep us covered." He ordered as he looked at each human ally in turn, each of who nodded in confirmation. He then looked to Raph and gave a nod.

Raph drew back the shuriken and tossed it hard. The throwing star flew through the air with only a slight whizzing sound that before the Kraang could react cut right through the small box device that Donnie said was causing the ultra-sonic signals and destroyed it almost instantly.

"The turtles have found the location of the area where we are conducting our extraction." One of the Kraang stated before they all started to fire their lasers at the team.

The four humans dodged out of the way while Leo and Aaliyah took the lead, using their longer weapons to reflect the laser blasts, regardless of whether it was away from them or straight at the Kraang, which did happen a few times. The other three turtles followed their leader and their friend.

They dove right in and started to cut their way through the Kraang droids, Donnie having extended the blade from his staff to make his naginata while Mikey was able to whack them hard enough with his nunchuck without using his kusarigama.

"Let's go." April said to Jennifer and the two of them started to move around the area to head toward their still unconscious rat master. Karai had her tonta waiting but was finding it hard to stand still. Casey dropped some of his cherry bomb taped hockey pucks and started to hit them out toward the Kraang.

"Kraang detects inferior weaponry." One of them stated right before he got blown in half.

"Inferior that." Raph sniped as he kicked the Kraang that was inside the droid and turned to the next one.

April and Jennifer made their way over to where Splinter had been laid out. The red head used her tessen to cut Splinter free and Jennifer was able to catch him. She was able to hold onto him easily but was glad that April was going to be able to help her out momentarily; carrying dead weight was not something she was accustomed to.

April did come over and took Splinter's left arm over her own body. "Let's go." She said and the two of them started over toward Karai, who was waiting impatiently still as Casey still covered the turtles.

"Looks like they're getting away." Mikey said. "Should we book it too Leo?"

"We should destroy that device." Raph interjected as he took out a Kraang droid. "Whatever they tried to get from Master Splinter, they shouldn't be allowed to keep it."

Leo nodded in agreement. "Raph is right, let's take it out."

Before they could move to do so though their came movement from the other side of the tunnel where thankfully their friends had not gone. Emerging from the tunnel was not only even more Kraang droids but even worse off was Kraang Subprime, who laughed. "We meet again, you hideous reptile freaks." He stated.

"Didn't we already ace him, twice?" Raph asked. "What the hell is he doing back here again?

"Dude, these guys always get extra innings." Mikey pointed out sagely. The problem was in this case he actually seemed to be one hundred percent right.

"Who is that?" Aaliyah asked.

"That's Kraang Subprime." Leo answered the female turtle. "He seems to be the second in command of the Kraang army."

April too had heard his voice and frowned just a bit as she remembered being the one to lead Kraang Subprime, in the disguise of what she thought had been her best friend Irma Langston, to the lair to escape Footbots that had attacked them. In reality though it was a decoy to allow them to find the lair and begin their second invasion, the one that had almost mutated New York and had caused them to run to her family's farmhouse for a few months.

Some of them started to turn and shoot out the two girls and their unconscious sensei but Karai jumped in front of them and started to deflect the blasts aimed directly at them with her tonta. "Don't worry; I have your backs, keep going." She instructed the two girls.

Donnie could see that even more Kraang droids were right behind Kraang Subprime. "I think we're going to have to let this one go." The purple masked turtle noted

"No way." Raph said.

"No, Donnie's right." Leo replied. "We can't get through all of these Kraang droids and Kraang Subprime too." He nodded toward the exit where the girls were leaving with Splinter. "Time to go." The five of them each took out smoke bombs and dropped them.

The Kraang droids tried to blast them with their lasers despite the smoke but they didn't seem to hit anything. When the smoke cleared the turtles and their human allies were gone.

"Forget them." Kraang Subprime ordered the other Kraang. "We have what we wanted from that disgusting rat." He walked over and with the Irma like hand took out a CD and lifted it up to stare at it. "Let's hope this information was worth it."

They returned to the lair. They set Splinter on the couch so they could keep an eye on him. Aaliyah retrieved a blanket to place around Splinter. Karai sat by her father's side with Jennifer sitting just above them.

"Is there any way to know what the Kraang took from sensei?" Leo asked Donnie.

The purple masked turtle shrugged helplessly. "Until Master Splinter wakes up there is no way to know for sure." He looked over at their father. "On top of that, if they didn't take anything but simply copied it then there is no way to know at all."

"I'm sure Master Splinter knows lots of things that could be useful." Jennifer noted as she looked to the turtles. "But what could be useful to the Kraang?"

Three of the turtles looked like they were thinking about that. Mikey was too but the truth was no one expected an insight from him. "I suppose the most likely thing he would have that would even benefit the Kraang in any fashion would be is martial arts knowledge." Leo answered.

"Yeah, he knows things that he hasn't shown us yet." Raph added. He remembered when Victor Falco aka the Rat King had first tried to take control of Splinter's mind and his lesson to them about hesitation leading to vulnerability had come back to bite Falco. Then Leo had made a comment about how they were getting as good as him and Splinter had used a move that planted Leo on the ground reminding them all that everything they knew he taught them, but he had not taught them everything he knew.

When he turned around and mentioned that to them it drew a small chuckle from everyone except for Leo who gave a mock glare at his red masked brother.

"I just wish we knew when father would wake up." Karai said. "Until that happens we can't prove that he's really okay."

Leo came over and placed his hand on Karai's shoulder. "Sensei will be fine Karai. He's pulled through much tougher than this. You should know, you were the one who stopped him from drowning when Shredder tossed him into the drainage system during the invasion." Leo tried to soothe.

"If it helps any his mind is now calm." April said to her friends as she took Donnie's hand. "I think he's just resting now. He is still recovering from the poison from both Snake Eyes and Parasiticaqueen."

"So I guess now all we can do is wait." Leo said softly.

Splinter sighed softly as he opened his eyes. He sat up to look around and was immediately enveloped in a hug by Karai as she gasped, "Father."

"I am alright, my daughter." Splinter assured her softly as he hugged her back. He then reached over and took one of Jennifer's hands and gave a gentle squeeze before he looked back and smiled at the turtles, April, and Casey. "Thank you all for coming to my aid."

"We'd never leave you sensei." Raph said to him.

"Do you know what the Kraang did to you?" Mikey asked him softly.

"I am afraid not Michelangelo." Splinter answered his youngest son. "I do not believe they actually took anything from me."

"If they only copied something then, we may never know what it was." Donnie said.

"Unless the Kraang decide to use that against us." Leo reminded them all grimly.

What are the Kraang planning? What did they take or copy from Splinter? Is there some other source at work here besides the Kraang? The adventure continues on.
