Casey: New York City after alien invasion. We returned to a broken almost deserted city courtesy of the Kraang. The Turtles and Lizzie invaded Dimension X to stop those alien freaks and undo the mutation of millions of people. Meanwhile I was sidelined like a chump salvaging food and medical supplies like it was the zombie apocalypse or something. I totally got ripped! Casey Jones should've been in that fight! And on top of that Lzzie has feelings for Leo and not me! Got to say though it's kind of cool how almost getting annihilated can bring the city together. Well most of the city. Then there's the others thieves lowlifes and thugs and worse Purple Dragons. I was able to convince Lizzie to come with me. I told her I needed her help but really I just want to show off. She won't be able to resist me after I kick there butts

Casey and Lizzie ambushed the purple dragons at the bank

Casey: Nobody steals in my town!

Lizzie: enough with the one liners!

Purple dragon: It's that vigilante nut and a freak! Let's crack them open!

The purple dragon's attacked but Casey and Lizzie took them down easily

Lizzie: not bad Casey

Casey: are you kidding? That was awesome!

Hun: your both brave for children

Casey: oh a new recruit! Ready to taste some asphalt scum?

Hun: Not a recruit. I'm the new leader. Hun

Lizzie: never heard of you

Casey: I think I prefer scum!

Casey tried to hit Hun with his hockey stick but he punched him against the wall

Lizzie attacked Hun with her scythe. He got out of the way in time but still got a cut on his arm

Lizzie: if you think you can stop me your a fool!

Hun threw Lizzie against the wall

Hun: you think your as skilled at shredder but you are just a spoiled little girl!

The purple dragons and Hun escaped the bank

Casey: God damn it!

Casey and Lizzie made it back to the lair which was a mess

Raph: look what the cat dragged in. Herself and Casey

Lizzie: not in the mood Raph

Raph: yeah well you never are. Where have you two been?

Casey: Doing what you should be helping the city stopping crime!

Leo: hold up. In case you hadn't noticed we just got back here

Donnie: Yeah we just happened to stop a little thing called a massive alien invasion

Mikey: We all deserve a little down time. how are you not tired Liz?

Lizzie: because I'm used to so much fighting

Casey: plus villain never takes downtime! We just took on the purple dragons!

Raph: So how bad you beat them?

Casey: Well at least we stopped them from getting away with the cash.

Donnie: Wait you didn't beat the purple dragons?

Lizzie: they new leader and he's as skilled as I am

Raph; Hahahaha! Really? You expect us to believe that?

Casey: You don't want to help? Fine! I don't need you guys. Casey Jones can protect the city alone

Donnie: good luck with that! Hahaha!

Lizzie: I'm going with you Casey

Leo: wait what? Lizzie this is revenge isn't it?

Lizzie: yeah and I'm going to get it

Casey: sweet! So this is also a date

Lizzie: No and just don't get in my way

They both left the lair and mikey could tell Leo wasn't happy

Mikey: someone's jealous!

Leo: I'm not! Lizzie clearly doesn't like Casey that way!

Donnie: you mean your girlfriend? I see why you guys do that now it's kinda fun

___________________________________

Casey and Lizzie went back to looking for the purple dragons

Casey: Those jerks. Whatever first up track down the stupid dragons and pound their new leader in his lame head

Lizzie: for once I agree with you

Suddenly they both saw shredder and the foot clan drive past them on a motorcycles

Casey: The Foot? Guess the dragons will have to wait

Lizzie: Hold on casey! The shredder will kill if you try to fight him! He almost did the same to me!

Casey: I can take that guy one on one! your way cooler as a mutant anyway and use my extra hockey mask so shredder doesn't-

Lizzie: No! I want my face to be the last thing the shredder sees before I kill him!

Casey: Ok! Ok! Geez...

___________________________________

They both followed shredder to a restaurant

Casey: wait here I'll see what's going on!

Lizzie: fine but don't say I didn't warn you

Casey snuck inside and came back a few minutes later

Lizzie: your still alive-?

Casey: That was close way too close! Oh man my heart's pounding so fast! That was so cool!

Lizzie: Casey! What happened in there?!

Casey: The shredder saw me but I was able to trick him! Wait until Raph hears about this

He started texting Raph what just happened

Lizzie: did you hear anything useful?

Casey: yep! Shredder's minions are heading to the docks

Lizzie: then that's where I'm going

Casey: I'm going to! With or without you!

Lizzie: fine but like I said before stay out of my way

___________________________________

Lizzie and Casey arrived at the docks to ambush fishface and Rahzar

Casey: Just wait until the turtles hear about this. Liz follow my-

Lizzie kicked fishface in the stomach and he dropped on briefcase

Lizzie: hand over what shredder stole and I'll go easy on you!

Rahzar: I'm not scared of shredder's daughter!

Just then Casey hit Ragzar in the head with his hockey stick

Casey: Lizzie your supposed to follow my lead!

Lizzie: are you seriously going to argue about this now?! You have no idea who these people are!

Casey: well they don't know who I am either!

Fishface: I grow tired of both of you-

Rahzar pushes Fishface onto the floor

Rahzar: I'm going to enjoy taking these kids apart piece by piece

Casey: Bring it on freaks. I'm not going down without busting a few fangs

Lizzie: I've beaten you before and I'll do it again!

Rahzar: you've gone soft Elizabeth-

Rahzar was suddenly crushed by a giant crate that Raph dropped

Raph: Come on!

Casey: hold up!

He tried to pick up the briefcase fishface had but couldn't

Casey: a little help?

Lizzie picked up the case easily

Lizzie: lets go!

___________________________________

The three of them made it back to the sewer lid

Raph: Have you taken too many pucks to the head? No way can you beat those two alone your lucky Lizzie was with you

Casey: I didn't need her help and stopped them from stealing this case didn't I?!

Raph: What's so important you'd risk your stupid life for?!

Lizzie: since the shredder what's this thing then it can't be good!

Casey: then let's find out!

Casey opened the briefcase and it was filled with chemicals

Raph: Dangerous chemicals good things we were throwing this case around. We'll take it back to Donnie he'll know what they are

Casey: No way you take it to Donnie I'm going after Shredder

Lizzie: so am I now that I know where he'll be

Raph: Lizzie do you remember the last time you went up against shredder?! You were mutated into a tiger!

Lizzie: that has only made me stronger and faster! I'm more prepared to face him!

Lizzie and Casey went after shredder

___________________________________

Raph went back to the lair and told the rest of the turtles and Karai what happened

Leo: Are you crazy?! You just let both of them go?!

Karai: how could you let Lizzie face shredder?! Do you remember what happened the last time she did?!

Raph: yes I do remember and I didn't just let her go! But what was I supposed to do chain her to a wall? I told them not to go!

Karai: I know Lizzie and words don't do much!

Donnie: well I have no idea what this chemical is. It's not mutagen based. Maybe it is an explosive the thing is we've seen stockman's lab and he doesn't have the equipment to use these chemicals

Mikey: what kind of place would have equipment like that?

Karai: the factory in china down. The chemicals there are radioactive

Donnie: good idea!

He looked up the factory on his computer

Donnie: yep It's the biggest chemical manufacturing plant in the city.

Raph: And if it's in Chinatown that means it's controlled by the purple dragons right?

Karai: doesn't matter. We have to take that place down

___________________________________

Meanwhile Hun showed shredder the same factory

Shredder: You've done well to bring this factory to my attention Hun. It will be adequate for my plans.

Hun: I have one request. Since this factory is on Dragon territory perhaps I should be in charge

Shredder: So be it. Success is to be rewarded as failure is to be punished

Suddenly a smoke bomb exploded then Lizzie and Casey showed up

Casey: Looking for us?

Lizzie: your not walking out of here alive shredder

Shredder: surrender now Elizabeth and I will spare your life

Lizzie: your dead shredder!

Casey: Hey I'm here to!

Casey used his electric glove to electrocute shredder

Shredder: You have spirit boy but I tire of this game-

Lizzie kicked shredder in the face right when the turtles and Karai showed up

Mikey: Oh yeah!

Shredder: Destroy them all! I need Elizabeth and Karai alive!

Casey: we don't need you guys. We had this!

Lizzie: just keep fighting!

Both Lizzie and Karai attacked shredder

Shredder: Foolish children I taught you everything you know. You hold no surprises for me!

Karai threw a smoke bomb in shredder's face and Lizzie kicked him in the stomach

Karai: This is it Shredder!

Lizzie: You are not going to walk away from this fight!

Shredder: I have no time for idle threats!

All of a sudden Casey threw a chemical into the vat and the whole factory started to shake

Shredder: NO! You fools!

The turtles lizzie Karai and Casey escaped and all chemicals exploded

___________________________________

The team made it back to the lair

Casey: you know Liz we make a pretty good team

Lizzie: I guess we do

She kissed him on the cheek

Casey: I-I knew it! You do have-!

Lizzie: just keep this between us alright?

Casey: you got it!

Lizzie and Casey walked up to the turtles

Lizzie: he really is a fool

Leo: who's a fool?

Lizzie: shredder. He never saw us coming

Leo: your right about that

Raph: Got to hand it to you Casey. You kind of saved the day

Leo: Not to mention you took on Shredder and you're still in one piece. With Lizzie's help of course

Casey: yep she's the best. I couldn't have done it without her but don't think I'm 100% a team player cause Casey Jones is still a solo vigilante of the night a mysterious lone hero in a world of evil

Lizzie: maybe with years and years of practice sure why not

Just then Donnie ran out of his lab

Donnie: Guys this is even worse than I thought. Shredder's mixture it's not an explosive!

Leo: So what is it?

Donnie: I think he's working on a mind control formula. If it works he could use it on us or every single person in New York City
