A/N: just a quick note, I apologize if the last chapter was a bit boring. I had to come up with something to make the two fight XD I bet you're all wondering why food is the next mutation. Well the answer..... Idk. I couldn't think of a good idea for enemies to strike and that was all I could come up with 😂 sorry. Now here comes the love expert! Please enjoy

He ran and ran and ran through every rooftop, jumping over some far distance of buildings, remaining to stay out of sight. Citizens didn't catch a glimpse of what happen on the top of the bulidings, which was good cover for the turtle to keep running. This wasn't normally like the purple clad turtle. Sure, he and Casey fight non-stop, but he didn't see his point in running. He was able to realize that when he finally stopped his feet.
He felt terrible. His brothers were only doing their job on helping April, and he felt like Raphael when he threw his temper. Not only that, he walked away, making Casey win their little argument.
He felt himself boil with anger as the thought of Casey came up. He panted heavily as he could hear the echoing of his laughter in his head, and growled annoyed from the sound. His stomach felt it was gonna explode with a disgusting feeling of vomit, his legs felt relief when the running was ended, and his heart.... His heart was thudding so fast. Perhaps not from the running. Perhaps from.... Something...
He growled to himself and sat up looking into the blue sky, seeing how wonderful it was. He thought of April when clouds were rolling by. "What does she see in him?" He asked himself. "Clearly he's just as aggravated as Raph, and he thinks that he always have to save the day. That terrible laugh and smirk is just..... just.."
He clenched his hands to become fists, and let his forehead winch tightly as he closed his eyes. Donnie began to breath in, trying to remain into his calm state. But it didn't seem to help this time. Nothing could.
"Dude..." A voice panted suddenly causing the purple clad turtle to jump. As turned back to search for any sight of another soul, but nothing was there. As he was about to walk away, he saw an green arm appeared and began to pull itself to get onto the rooftop. It pulled over a body of green and with a shell, panting and sweating as he laid on his back. "You.... You run too fast when you're mad dude..."
"Mikey? What are you doing here?" Donnie asked as he walked over to help his brother stand again.
As Mikey stood up and was panting lesser, he finally spoke. "I followed you bro. Bros gotta stick together whenever one splits up from a bad fight. I even brought you a slice of pizza." Then the orange clad turtle handed over to his brother a freshly cook slice of pepperoni pizza. It didn't have any mess upon it, or smelled bad.
Even though Mikey makes silly things to cause anger, this was probably the one time he didn't really screw up his comforting. He was always there for Donnie, just as he was always there for his little brother. The turtle let his gap tooth reveal as he smiled and took the slice. Then he looked upon Mikey and said, "Thanks Mikey."
"Like a turtle do." Said the goofy one as he grin widely. But his grin had disappeared as he opened his eyes again to Donnie revealing the blue. "You okay bro?"
"I'm fine, really." He said as he sat down and laid his shell against a square hidden stairway. "I just.... Jones really likes to get under my skin. If only he would understand, you can't just attack and think you are the only one doing something right. We all were working together. And he started it!"
Mikey laughed at the sound of his brother on the last sentence. "Dude you sounded like a little boy."
"Yeah I know." He grinned admitting to himself that was funny. "It's just, I can't get Jones out of my head ever. I don't see what April sees in him."
Mikey's eyes grew wide, and he looked back at his brother with a face of concern. "Really now?"
"Yeah, that's why I screwed up in the dojo. I kept seeing him, and I just.... Pooped out! I just can't stand to see that annoying smirk he grows every time he's tries to act cute, especially towards April! And I can't stand his annoying laugh, and the Goongala thing, that is getting annoying! Booyakasha is even better! And now thanks to him arguing with me, we probably just doomed half of the city! I can't stand him!"
He let out a deep breath as he finally let out his yelling words of the human boy. He felt more relieved getting it out instead of leaving it in. Donne felt the image of Casey appear, but finally let his mind become free again. As he was finally calm with a soft tone, he said closing his eyes, "I'm sorry. I had to yell that out. I just don't fully know how to handle this, and if I don't, April is not gonna be happy about it at all." He then let out a small smile as he was feeling like himself again. "Thanks for running after me Mikey."
But when the purple clad turtle looked back toward his little brother, he jumped as he was having full eye contact into the blue of his brother's eyes. He was stunned of the strange look upon Mikey, and lifted his head back to get his space again. "Uh, what are you doing?"
"Just listening." Mikey said not blinking once. "Very closely....... Bro...."
Donnie was not to sure how to react to this. Mikey is a goofball at times, but this was just completely strange of him. He almost looked fascinated by Donnie's yelling. Very odd...
"Anyway...." He said unsure. "I gotta find a way to not fight before April gets back."
"Uh huh." Nodded the orange mask turtle as he still looked towards him closely. Finally feeling the aching in his eyes, Mikey blinked finally and leaned back growing a grin in his teeth. "So Donnie, how do you feel when you talk about Casey?"
Puzzled, Donnie only looked upon Mikey letting his brow go up. "What?"
"How do you feel when you talk about Casey?" He repeated with a serious look, as if he was French looking.
Still the purple clad turtle was stunned, but he decided to answer. After all, Mikey was the one to run after him and listen to him. "Well, I get so upset, my stomach turns and twists, my heart especially. It thuds too fast for my emotions get the best of it, I could easily get a heart attack from the speed pace it gets to amount of dange-"
"Does your stomach feel like someone punched punch you really hard?"
Donnie just looked stunned again towards the younger turtle. What point is he getting at? "Wha... Yes, Yes! My stomach feel like I've been punched. What's the point?"
Mikey's eyes grew wide once again as he stared toward his brother. Then came a giant smile, but it was hiding behind his hands as they clenched and were raised closely to his cheeks. His eyelids lit up as he kept looking towards the purple makes turtle as he looked very confused.
Donnie was about to ask again if Mikey was alright, but then he heard the sound of small snickers escaping from his brother. Then a burst of laughter jumped Donnie from surprise. He looked at his brother again, only to find him laughing and cooing with 'awwww's. This was definitely strange behavior, even for him.
"Dude! Dude dude dude!" Mikey chirped wiggling his legs.
"What?!"
"I think I.... I..!" He finally panted calmly letting himself breath. Then he grew a face of being serious as he looked back to Donnie and said, "I think I know what the problem is between you and Casey."
This gave curious feelings to Donnie. Normally he wouldn't care of what the situation is, even if he could figure it out on his own. Also the fact it was coming from Mikey, it would almost seem pointless. But sometimes it's possible for the goofy one of the team to be correct. Maybe he knew the problem and he could solve it. "Okay. What is it?"
"I think, you my brother, I love you no matter what bro, but I think..." He then took a moment of silence to make a still face as he closed his eyes.
Waiting patiently, Donnie watched his brother stayed silent. He waited for his brother to answer, but it seemed Mikey had dozed off while his eyes were shut. Impatient, Donnie yelled, "Well what is it?!"
Mikey opened his eyes remembering his brother was still there. "Oh. Right, I was talking."
Giving himself a palm to his face, Donnie felt his brother couldn't possibly knew the answer. As he about to speak, Mikey's answer gave him the face of horror.
"You're in love with Casey Jones. LBGT turtles for life!"
Donnie jaw fell as he stared at Mikey. He was speechless, shock, and couldn't move from the horror answer his brother gave him. This couldn't be real. This was just a joke. But it was obvious Mikey wasn't joking.
"That's your theory?" He asked him. "You think I'm in love with some psychotic moron?!"
"Actually dude, psychotic means suffering from sadness and obvious Casey isn't-"
"I am not in love with him Mikey!" Donnie shouted. "That is completely ridiculous. How could I possible 'love' him? Ow! See? Saying it hurt!"
He gasped feeling like he knew the pain. "How badly did it hurt?"
"That's not the point! What's given you the thought I'm in love with him?"
"Well, from experience of our old cartoons, it's like the romance of anger. Some humans hide their feelings by being bullies and pretending they don't care for that one person they pick on. It's a way to hide their true feelings to the other person, and feels it's the way to let them hide until they come out to say the truth."
Donnie was completely unspoken. This could not be true. It couldn't be. It's completely stupid to the genius. How could this even become possible. "Okay," he said before another loud time escape. "You have been eating to many pizzas that have been hidden under your bed. That stuff goes bad you know. I know for a fact I am not, repeat, am not, in love with Jones, and this conversation is over."
He began to walk away along with his brother second behind him. "Come on dude!" He said as they began their walk back to the lair. "You can't deny it, otherwise it'll get worse, especially if you grow jealous."
Donnie only groaned at every theory his brother made. It was a way to get them both back underground, though it wasn't pleasant. He kept on thinking as Mikey kept talking of the theory.
Could it be true? But why would he? What does Jones have that could possibly make him switch his feelings away from April?
But he knew he was right and his brother was a lunatic. He was not in love with Jones.
