I do not own Teenage Mutant Ninja Turtles. I only own Cassie.

Story Start

"Next time, I'm driving," Cassie kept muttering as she was being held by Leo along with Vernon and April. Raph lifted them up and Cassie immediately started crawling away from the ledge and glaring at Vernon.

"It wasn't my fault," Vernon shouted as he watched Cassie crawl over to Donnie, and she hid behind his legs.

"Doesn't matter, you were in the driver seat so she's going to blame you," April said with a roll of her eyes before watching curiously as Donnie bent down and calmed down Cassie. "Must keep an eye on that," she thought with a smirk before everyone focused back on how in the world they would get down this hill.

"Are you all right?" Donnie asked Cassie quietly as they descended the mountain to get to the tunnels underneath the cabin.

"Not really but I will be eventually. If I get to punch somebody in the face then I'll feel so much better. You distract April so I can hit Vernon," she said sneakily and laughed when Donnie immediately grabbed her around the waist and held her close to him so she wouldn't go attack the camera guy. "I was just kidding, but I will totally hit a Foot Clan ninja," she said and chuckled again as he held her tighter to him.

"It's too dangerous," Donnie whispered in her ear as he ignored the looks from his brothers. "I don't want you to get hurt," he told Cassie before letting her go, but he even shocked himself when he held her hand and they walked together. He was happy when she did not pull her hand free from his.

"All right, I won't risk my life too much, but if we survive this, then we are going on a date together," Cassie told the now blushing turtle with a wink. "I've always wanted to date a ninja," she said and chuckled when he shook his head at her but he was smiling.

"All right, love birds, we have a city to save," Raph shouted before they all jumped into the tunnel and slid all the way to the city.

The ride through the tunnel was a lot more fun than the crazy drive in the tractor trailer, but Cassie still held tightly to Donnie so she wouldn't go into the wrong tunnel or get hurt. She would definitely have some bruises but nothing too bad. Sliding through a sewer tunnel when you're not super human would definitely leave bruises.

The group made their way into the Sacks building and the turtles immediately tried to get the humans to go home and be safe, but of course, Cassie and April denied. April grabbed Cassie's hand and they took off running with Vernon to get the antidote from Sacks. Cassie yelled good luck to the turtles before they disappeared out of each other's sight.

Cassie's nerves were on edge as they quietly sneaked into Sacks' lab. She glared when she saw the man standing in front of a large vial that was full of a green ooze. "Now if only I had a rock or something," she thought before smirking when he saw a glass beaker near her. "This will work perfectly," she thought when she picked it up and felt how heavy it was.

"April, Vernon, get down," she whispered to them quickly before standing up and chucking the beaker straight at the back of Sacks' head. "Bulls-eye," she thought with a smirk as she grabbed another beaker and quickly threw it at his face when he turned around disoriented.

"Are you crazy?" April snapped as she watch Eric Sacks slump to the ground and he wasn't moving.

"Yes, but my craziness is useful," Cassie yelled back in return as she rushed over to the unconscious man and tied him up with a nearby cable so they could call the police. She finished typing the man up while April grabbed the vial from the machine.

"We have to help the guys," April said before ordering Vernon to watch Mr. Sacks and call the police. April ran up the stairs first with Cassie right behind her.

Cassie's eyes almost jumped out of their sockets when she and April reached the top of the building. The guys were holding up a large metal tower while Shredder was flinging blades at them. She glanced over at her cousin, who looked ready to say something. "Hey tin can, pick on somebody your own size," Cassie yelled and then April yelled a threat to throw the serum into the city below.

"No, don't," Donnie yelled fearfully as he watched Shredder start making his way towards the girls. He looked to his brothers and they had no choice but to release the tower and head for Shredder. Donnie's heart was racing a mile a minute as the tower crashed off the side and into another building at the same time that Cassie, April, and Shredder went over the side. "Cassie," yelled as he and his brothers dove off the side of the building as well.

Cassie cursed as she crashed into the broken part of the tower. Unfortunately, she was a lot closer to Shredder than her cousin was, who was yelling way too much. She should have been yelling for her life, but she was too busy trying to kick the serum out of Shredder's hand. "Drop it already," she grumbled before hissing when Shredder kicked her in the side under her ribs. "That's it," she growled before releasing the bar she was holding onto and launching at Shredder. She felt her skin being cut by his armor but not too badly. With the way she had tackled him, he couldn't really move much, so she was able to reach over and kick the serum out of his hand.

"No, we need that," April screamed and Cassie cursed when her cousin dove for the serum.

Shredder let out an angry roar as he shoved Cassie off of him and she started falling as well. However, Shredder didn't expect for Raph to throw one of his sai at his face, which impaled the man between the eyes. His hands slipped off the tower and he went plummeting down to the street below.

The turtles formed a chain with each other's body so they could reach both of the girls. Raph was just barely able to grab April and Cassie's hands. He and the others swung their bodies so the girls could latch back on to the broken tower. Everyone grabbed hold of the tower and just in time because the broken part of the tower started to fall slowly towards the ground.
