*Casey and his wolfwalker Sister Ashlyn Arrives at the turtles and the wolfwalkers lair as they both looked around*

Donnie-If this purple ooze was injected into Bebop and Rocksteady's bloodstream, it's feasible that were I to pinpoint a singular isotopic signature 

Robyn-Donnie and I may be able to use it to track their location.

Casey-And if we find them, then we find Shredder Put them all in shackles!

Raph-And as long as we all have our hockey masks, what could go wrong?

Casey-Seriously? Now I'm taking wardrobe advice from a bunch of Swamp Things...Hey! Living in an underground amusement park and of bunch of wolf sleeping creatures or whatever

Mebh-it's pronounced WOLFWALKERS!

Casey-and have, forgive me, the most pretentious names ever

April-Uh, excuse me, I named them

Robyn-yeah!

*Casey sees splinter in the back room*

Casey-Hey, guys? Nobody move. Don't move! Ashlyn don't move! There is a giant rat back there.

Raph-Yeah, we've, uh...

Mikey-Mmm-hmm

Raph-Seen him around here before

*Leo shakes his head and mouthed no*

Raph-You know, there's only one way to get rid of him You got to get low.

Mikey-Low! Yeah

Mebh-yeah

Raph-When you go at him, you got to go fast, and you got to go hard.

Mikey-We believe in you, Casey Jones. It's all you, bro.

Raph-Exactly. We need you to get him.

Mikey-Three, two, one, go!

*Casey charges at splinter screaming until he gets knocked down*

Splinter-Giant rat, 1. New guy, 0.

Raph-I can't believe it was that easy. I almost thought he wasn't gonna do it for a second.

Mikey-Good stuff. Good stuff We should really have people over more often.

April-You're leaving?

Casey-If Ashlyn and I can find our way out of here, I am. You know, I was doing just fine tracking Bebop and Rocksteady, and then you just T-boned my existence. So now I'm gonna find them or I'm gonna go down swinging.

Robyn-Casey...

Casey-No, it's like they say, "If you want to get work done, don't spend time at the zoo."

*Casey sees the boys' truck*

Casey-"Tartaruga Brothers"? That's the...That's the truck. It was them Who are these guys?

April-These four have done more for this city than you will ever know or they will ever take credit for

Robyn-So if you want to go down swinging, these guys hit harder than anyone

*Casey and Ashlyn were on their way home until foot ninjas jumped out throwing a large giant net over wolf Ashlyn throwing her in their truck as Casey was occupied with the foot ninjas as he couldn't get to his sister*

Casey-ASHLYN! NO!

*from Casey's throat actual wolf growls came out as his wolfwalker spirit flew out as his sleeping body fell to the floor. his wolfwalker spirit turned into his wolf a russet and brown wolf

wolf Casey looked down on his grey scented covered paws then to his sleeping body as he bolted off after the car holding his sister whining out to her to him he's calling her name*

wolf Casey-ASHLYN!

wolf Ashlyn-CASEY!

*Casey stopped as he knew he couldn't run anymore as he was catching his breath*

Casey-GUYS!

April-Casey! your back! what's wrong?

Casey-it's my little sister Ashlyn the foot clan took her!

everyone-WHAT?!

Casey-we were on our way home until the foot ambushed us taking her away inside a large net. I passed out for one minute and the next thing I knew my eyesight was different! I could see what I could smell and I could see my body on the ground covered in my scent! but then I had paws!

Donnie-I thought I fixed the bite?

Mikey-guess not. OW!

*Raph slammed his fist on Mikey's head causing him to rub his head*

Leo-don't worry Casey we'll get your sister back but you should bring her sleeping body here where it's safe

*Casey nods*

Mebh-Casey

Casey-yeah?

Robyn-your one of us now a wolfwalker

*Casey slowly nods his head leaving to bring his little sister's body to the lair*
