Just A Little Head Canon :>

Just a little head canon :>

So in one episode (can't remember which) Casey breaks a rib or two. Casey being Casey decided not to go to the hospital and there for his ribs never healed correctly. So now everytime he sneezes, or coughs really hard, Casey gets a jolt of pain. The others have told him to go to the hospital but Casey still refuses

You know with all the ships I've seen Casey in all I can think about is how he took the Skittles commercials way to seriously...

This is a joke-

Here some more endings for you @starlightshadowsworld my friend

This is from what @nrrrdgrrrl2002 said in the comments also my spin from the mutagen drug story they made too.

"Ugh-" Casey kick an empty water bottle across the alley, then cried out annoyed, "there's nothing to do!" Donnie look over at him, "Isn't that good? I mean if no crime is happening then no people are getting hurt." Casey paused then said, "I hate to admit that you have a point...but no crime-" a secretary alarm cut him off. "Let's go check that out guys." Leo says as he began to claim the fire escape.

Getting to the site the group of teens see what cause the alarm, purple dragons. Casey was expecting Leo to say something like 'Okay team let's go into this carefully' or something like that, but none of that came. Everyone just jumped into the fight without any regard, shocking him. He jumped after them not wanting to miss any action. "I'm glad for an easy fight!" Raph started, then he hit one of the dragons over the head, "I'm still sore from yesterday's training!" Mikey chimed in, "I'm with you dude! Easy fight means an easy wi-" Mikey was knock into a dumpster causing it dent. "Mikey? Ah-" Donnie started but he was flung into a nearby wall, almost everyone was. It took a few seconds for everyone to gain their bearings and it only a little bit longer to see what hit them. A mutant. A new mutant. The thing was huge, its tail was about the size of Raph, not to mention it's claws. "W- what is that?" Casey asked not really wanting an answer. "I have no clue, but it isn't friendly..." Mikey says quietly. The mutant head did a full 180, when it heard that they were all awake, it's body turned very soon after that. "Everyone move!" Leo shouted when the thing started to charge that them. The mutant hit the wall face first just barely missing everyone. "Do we fight it?!" April yelled still on the floor. "Can we even fight it?!" Mikey asks. "We need to try! It can't just run loose in the city!" Leo yelled back.

After a long fight the mutant got away with the dragons. "I- is everyone okay?" Leo asked out of breath from the fight. There was a out of breath yes here and there and some nods. April looked over at something then said, "Hey guys...I think they left something over there." She pointed to something by the dumpster. It didn't take long to see what she saw, it was something glowing. "The hell?" Casey said also staring. Donnie walked over to the dumpster and carefully uncovered the glowing object. It was a bunch of syringes full of mutagen. "Woah..." Donnie says, "Hey Raph, Casey do you think that you could carry this?" They look over the crate of mutagen. "Yeah we can" Raph says, Casey nodded in agreement. Raph looked the crate over, "Hey put those syringes in you jacket pocket and then help me with the crate." Casey did what he was told not really caring much about the possible problems that could happen if one of the syringes happened to break. Once the group was that the lair the syringes were placed in Donnie's lab. April and Casey went home to tired to continue with anything after the fight.

A few weeks later Casey had ran into the dragons again but wasn't able to beat them in a fight. His eye was already bruising when he had entered the lair. When the others asked what happened and when he explained the others all started to laugh. "How did you lose that badly?" Raph ask in fits of laughter. "To the purple dragons too!" Leo added. "Did you lay down too fight them??" Mikey chimed in. "He probably helped them by kicking his own ass!" Donnie says with his own laughter. Casey left the lair after that, while tears threatened to leave his eyes.

When he reached his apartment, he fell onto his bed and cried. To Casey's luck his dad was out on the town and his sister was at daycare. While crying Casey lifted his head and saw something glowing, he wiped his eyes and went over to investigate. The glowing was coming from one of his jackets. Casey carefully put his hand into the pocket and pulled out a syringe. "Woah...guess I forgot to give this to Dee." Casey chuckled. He got up and put the syringe into a drawer out of reached from his sister, he give it to Donnie in a few days. Though the next few days weren't the best for Casey. He was still being laughed at by the turtles and school hadn't treated him great either.

A week after these incidents Casey had stormed out of the lair in the rain and cold. Getting into his room Casey tried to calm himself down but his efforts were in vain. He was far to hurt emotionally and some what physically to think clearly, his eyes fall upon at drawer. His thoughts clouded by emotions he pulled open the drawer and pulled out the syringe. Casey hesitated for a second but with emotions running high he stabbed it into his arm.

Pain instantly shot through his body and he curled himself into a ball. Casey body started to change in unnatural ways, and he screamed until he vomited. After what seem like hours the pain finally stopped and Casey felt something was off. Something physically and mentality. He looked over to a mirror. "Holy fu-" Casey started to say his voice raspy and hoarse, but he was interrupt by the door to his apartment opening and his dad's drunken voice yelling if anyone was home...
