Sacks stumbles over his feet, knocking over the table. Amy pushes ice at him from her hands, snarling. He rolls out of the way just before the strike hit him. Instead of his face, her ice daggers slice clean through the monitor. Scrambling to his feet, he hits the emergency lock-down button, sliding under the toxin shield. Alarms blare throughout the facility.
She speeds past pieces of glass and she looks to see that she was back to normal. Amy runs and looks down to see Raph fighting Shredder. She slides, stopping in front of April, Emily, and Vern. "Amy!" they exclaim. "Can I join the party?" she asks, grinning. Emily hugs her daughter. Hearing a grunt, she looks down again to see Raph on the ground. "Raphael!" April shouts and Shredder, hearing the scream, looks up. "You," he snarls. "Focus on me," Raph tells him but he gets knocked down. Vern sees the three trapped turtles and looks back at Raph. "Three…Four total turtles. One's fighting a robot samurai. Why?" Vern mutters to himself.
April and Amy run up to Donnie, slamming on the cage with their hands. "Donnie! Donnie! What do we do?" they shout and April presses her ear to one of the holes. "Adrenaline," he murmurs, but they couldn't hear it. "What?" Amy asks, pressing her ear to another hole. "Adrenaline," he says more loudly and they see a machine near them. "Adrenaline…" Amy whispers, forming an idea. She whispers in April's ear and she nods.
Vern looks down at Raph, who wasn't doing so hot with Shredder. "He's going to kill him," Vern murmurs and Emily gives him a glare. April taps the adrenaline button many times until it reads 'Adrenaline Overload.' They wait until they hear rapid beeping. Donnie gasps and they look at him. Leo and Mikey do the same, panting heavily. "I think you guys should move," Amy whispers to them and they nod dumbly, backing away a bit.
Amy raises her hands above herself and freezes the cages. They jump out of them one by one, breaking the ice.
"Oh! I feel really good right now! I feel like running!"
"I feel like cleaning! Who wants to clean the dojo? I'll clean the dojo!"
"Endorphins! Endorphins!"
Amy had to laugh, that adrenaline was making them insane. Leo hears her and wraps her in a hug. He spins her around, laughing. "Ames! You brilliant, gorgeous, amazing girl!" He reaches for her hand and waist, dips her, and kisses her full on the lips, ignoring the muffled shout of surprise from her and the surprised looks of April and Vern. Emily, however, gave a happy look. Leo pulls back and helps her stand up, beaming.
"I love you! Let's get Raph!" He and his brothers jump down. Amy blinks slowly, pointing between Leo and herself, trying to figure out what just happened.
"W-What…?" Vern pats her shoulder.
"That, kid, is the start of womanhood." Amy blushes, shaking her head. "Aww, my baby girl's got a boyfriend!" Emily exclaims and Amy turns redder.
"Ohh, I'm sure that was just the adrenaline talking," she says in a high-pitched voice and jumps down to the turtles. Raph slowly stands up, his brothers running around him. They were talking at the same time, but he was able to get the gist of it. Shredder was going to poison New York, Sacks was going to use mutagen from their blood as an antidote…
"So we've got to get going now!"
"Good. Let's do it for sensei," Raph answers, a toothpick in his mouth before they start running.
"Okay. We're going! Everybody calm down! Look how calm I am!" Mikey shouts excitedly as they make it outside. They made it just in time to see a helicopter take off. "Sacks is airborne!" Leo shouts. Amy growls, ice coming from her hands. Emily puts a hand on her shoulder and Amy calms down.
"Flight time to Manhattan, nineteen minutes!"
"Get us out of here, Donnie!" He lowers his goggles, scanning the trucks. His visor switches to a soldier.
"Oh my gosh! They have guns!" Donnie shouts in panic and Amy snickers.
"Get down!" They huddle around April, Vern, Emily, and Amy when the men start shooting. With actual bullets. Amy's eyes widen when she looks behind Leo to see the bullets ricocheting off the shells and back at the soldiers. Leo laughs.
"Ha! Are you guys okay?"
"We're bulletproof."
"Sweet." Amy chuckles.
"Can we get out of here now?" Leo nods and points towards Vern.
"Can you drive that truck?"
"Yeah!"
"We're on Raph. Ready?" Raph runs out backwards, grabbing a soldier's gun. The others run around him, following his lead. Amy flips out, landing on one man while throwing ice at another. The man under her collapses. "Everybody in the truck! We gotta go, go, go! Move!"
Leo grabs Amy's hand, throwing her into the truck before him. Donnie catches her, setting her on her feet. Raph bangs on the window. "Drive!"
"I'm on it!" The truck starts up.
"Come on, come on!"
"Ah, that's all I need. A backseat driving, talking turtle."
Amy giggles and Vern drives the truck straight out of the gates, slamming into and through them. Amy wobbles and gets thrown outside the truck. She grabs the edge of the truck, screaming. Leo inches towards her as she struggles to hold on.
"Grab my hand!" Amy looks at him before doing as he said. He slowly pulls her back into the truck. She sighs in relief.
"Thanks." Leo smiles. Mikey leans down from the roof.
"Where are we going, guys?"
"Donnie, what's the fastest way back to Manhattan?" Leo asks, turning to the genius brother.
"We just need to stay on this road. If we can get to the maintenance hatch at the bottom of the hill, there's a sewer line 2.4 miles from here." Leo leans out.
"Mikey! Let them know up there!"
"I'm on it!" A few seconds later, Amy hears a groan and then something else.
"Missile!" Her eyes widen and the projectile hits the side of the truck, sending the occupants flying. Raph falls over Amy first but then was thrown off when Vern tries to compensate. Emily struggles to hold onto her seat, praying that the turtles and Amy were okay. Amy slides towards the end of the truck, digging her fingernails into the sheet metal. Just before she could breathe a sigh of relief, Leo slides towards her. He crashes into her, sending the two out of the truck. Amy gasps and since Leo was on top of her, she shields him from the snow, pulling him closer protectively. She lands on a boulder, groaning in pain.
"Ames, are you okay?" Leo asks in shock. She saved him. She saved me. Amy rubs her back before nodding. "Oh, I'm gonna feel that later," she murmurs.
"Guys, move, move!" Leo rolls over Amy, shielding her as the truck runs over them. He then rolls them both out of the way of the tires. She looks up at him with a smile. Leo grins back before they stand up, staring down the slope. The duo start to run just as the Humvees chasing them runs over the snow bank.
Leo jumps, curling into a ball. He grunts when his carapace hits the windshield. Amy jumps onto the roof of the car, anchoring herself on top.
"How far off course are we?" Raph asks.
"Actually, we're on bit of a shortcut. But we need to keep going down. Straight down," Donnie explains. Mikey lowers his head in front of April and Vern.
"Hey! Just…keep…going…straight!" he tells Vern, out of breath. He turns to April. "What's up angel cakes?" he asks before leaping back onto the roof. Emily blinks rapidly. "Okay then…"
"Fire!" Amy looks down to see one soldier shoot an electric cable at Leo. "NO!" she screams before she falls off the car, tumbling down the snow.
"Guys, Leo and Amy are in trouble!" Mikey yells, having seen the whole thing.
"My shell's cracked. Just tape it up," Raph tells Donnie, ready to help. Donnie turns to Raph. "Allow me to be the bad-ass for once," he explains. Raph looks at him and he nods, sure of himself. Donnie backflips out of the truck, hollering. He lands next to Leo, who was unconscious. "Where's Amy…?" he murmurs, looking around before turning back to Leo.
"Hang on, Leo. Disengaging." Donnie pulls out his bo staff once his brother is secure with him. "God, I've always wanted to try this." Donnie slams down his staff, making a car fly over them.
"I got you, brother. One car down, two to go." Donnie is then shot with electric cables.
"Mikey!"
"All right, that's it. I'll take it from here!" Mikey uses his skateboard to jump to a car. He punches through the roof and grabs the steering wheel. "Whoo-hoo! Raph, I'm driving! Yeah!"
Raph flips into the neighboring Humvee, crashing through the rear-view window. The driver hits his head on the wheel.
"Where's ice princess?" Raph asks, not seeing her with them.
"I don't know, she was right here-"
"WHOO HOO!"
They turn to see Amy riding on an ice snowboard. She jumps up, flipping in the air before landing next to them. "This is awesome!" she shouts and Mikey beams at her sudden arrival.
"Hey baby cakes!" She chuckles at him. A smash made her look up. The truck crashes through a snowbank, jumpstarting an avalanche. Mikey stayed on top of the truck. He lands next to Leo and Donnie and Amy abandons her snowboard, sliding next to Mikey.
"Come on, Leo! Wake up!" They begin slapping him.
"Yeah! If you wake up, I promise to do anything you say!" Amy shifts as she slides down. She hears a gun getting ready and she turns to see a Foot soldier aiming a gun at her. "LOOK OUT!" Raph shouts.
She covers her head with her arms, waiting for something to happen. But nothing did. Confused, she looks up to see an ice shield covering them from the bullet. She gapes in shock while Raph and his brothers cheer. "That was awesome!"
"Guys! Shredder's chopper is 20 miles outside of New York City airspace!" Raph rolls his eyes.
"Thanks for the traffic update, Donnie. You doing sports and weather next?"
"If you're going to be nasty about it, then I guess you don't want to know that there's a 500-foot drop-off in 53 seconds!"
"Are you saying there's—" Leo jumps up.
"A cliff!" He sheathes his katana that he somehow managed to hold onto while unconscious. "We gotta get April and Emily out of there! Raph! Heads up!" Leo climbs up onto the truck, using Raph as a stepping stool.
"Don't forget that old guy!" Amy looks down at Donnie and Mikey. "Gimme a boost!" They nod and they bring their hands together. She steps on them and they steady her. Amy gives a thumbs up and they push their hands up, flinging her onto the roof. She meets Leo on top.
"Need some help?" He smiles gratefully at her.
"Thanks. Let's move." They run together on the roof, Leo dropping on the passenger side. Amy pops her head next to Vern, her hair flying to the side. "Hi Mom, Uncle Vern!"
"Change of plans." Both outside riders look up at the sound of a weapon powering up. "Oh come on." Since Amy was in front, she makes an ice shield in front of her, blocking the cable. She sighs in relief before another one comes for them. It attaches to Leo's plastron. Amy growls and pulls the cable, knocking the man holding it out of the car. Leo jumps out of the car with April and Amy grabs Vern and her mom.
"Mikey! Grab the cable!" The youngest turtle scrambles through the snow, searching for it.
"I got it! I got it!" Amy looks up to see the others barely out of range of the truck. "Hold on, hold on!"
Mikey trips over a rock, losing his grip. "Oh, no! No, no, no!" Leo, Amy, Emily, Vern, and April tumble over the edge. Mikey bows his head.
"Oh no…poor Leo, April, Amy, Emily…and that other guy. They were so young, so beautiful." Raph slides by.
"They ain't dead, numb nuts."
"Oh. Right on." Amy rolls her eyes as she holds onto the edge of the cliff with Vern and her mom. The cable had wedged itself between two rocks. Leo was holding onto the anchor, while April holds onto him. He looks at Amy in shock, since she was using her hand and carrying Vern and Emily at the same time.
"I hope you got a parachute under that shell!" Donnie looks over the edge.
"Hey, guys! It's the maintenance hatch! Our ticket home!"
"Great…now would you help a girl out, please?" Raph grabs Leo's hand, hauling him and April up. Donnie helps Amy, Emily, and Vern. She sighs in relief, brushing snow off her clothes.
"Guys, we gotta hustle! Shredder's over New York City!"
Amy tries not to cry out in pain as it shoots through her back. Must be from when I hit my back on that boulder. Leo tightens his grip on her, leaning his head down.
"It'll be alright."
Amy smiles softly and wraps her arms tighter around him. He kicks open the door to the ventilation hatch, landing on his feet. He sets Amy down gently next to April, Emily, and Vern. "Alright, listen up. We gotta find the elevators and get up to the roof."
He looks back at the others. "You guys get out of here. Get to a safe distance." April shakes her head.
"No, no, we can go find Sacks and get our hands on the mutagen as a contingency plan, just in case…you know." Raph rolls his eyes.
"Thanks for the vote of confidence."
Leo steps up to Amy. "Ames, if we don't make it back, bring the mutagen to Splinter. It can save his life," he tells her. She gives a confused look. "If? But-" he grabs her shoulders.
"Please! Just promise me." Amy looks up at him with tears in her eyes before nodding. Donnie steps up.
"Sacks' laboratory is on the 37th floor. I've already disabled the security system. Oh, and uh…" he shrugs uncertainly. "Good luck." He smiles awkwardly before running after his brothers. Mikey turns to them. "If I don't return, remember me, April. You can always find me…in here," Mikey points to April's heart and his brothers whisk him away. Before Leo could move, Amy places her hands on top of his. Suddenly, she kisses his cheek.
"That was for saving me. And this," she pecks his lips. "Is for good luck." Leo blushes, nodding slightly. She smiles at him, releasing his hands. "Go kick some metal booty." Leo smiles back.
"I will." The groups split and one member in each wish for the return of someone else.
