"Leo… I'm ready…" Mikey said. He squeaked when he felt a warm touch around his hips.

"Seriously, Leo, stop being a ghost ninja!" Mikey wailed. The ghost just chuckled and snuggled behind. "So, why you call me?"

Mikey sighed and turned around.

"I know how you died."

"Hmm…" Leo hummed. "Okay, Mr. Michelangelo. How did I die?"

"Don!" Raph ran to catch the emotional Don walking back to the lab. "Don!"

The purple banded turtle gets on the door and attempted to close it but Raph is fast enough to squeeze himself.

"Don! Listen to me! I'm sorry!" Raph said as Don turned around and sat on his chair.

"Leave me!"

"No!" he shouted. "Not until we get this straight!"

"I get it that I will never be loved back by anyone!"

"Someone loves you more than you think, Don!"

"Who then?"

"I AM!"

Donnie's eyes widened. So it's true. Raph did love him.

"… Forget it." Raph said as he went to the door.

"For about time you said it."

The grumpy turtle turned around, only to be welcomed by Donnie's embrace. Raph just kept frozen. Is Donnie really hugging him?

"Wait…" Raph pulled Donnie back and got confused. "You knew all along?!" he gritted. He had all emotions of anger and embarrassment all bottled inside.

"No, Raph… I had my guesses. I'm not putting my hopes up. But I observed your actions, especially if I'm with April."

"You tricked me!"

"No! I really waited for you to finally say it. I really hoped!" he said as his tears fall down. "I really wanted to be loved by Raphie… As he is the one I first fell in love before April."

Raph is surprised by what Don said. That he had loved him before.

"But I know you didn't see me that way before. That's why I kept it inside." Donnie suddenly felt strong arms around him.

"Do you still love me?" he asked. The brainiac just nodded. "Always." His tears are dried up as his hands went to Raph's shell.

"Master Splinter said I was a sickish baby and you're often by my side." He started to talk as Leo listened and nodded. "You did everything you could to make me feel better. Then, you found a permanent cure." He said as he placed the picture of the woman. Leo just stared at it. "She had it." He pointed.

"Karai had a deal with you. You know, the usual what villains do. You brought me topside for the cure. But… She lied to you. I assumed it's a trap and you protected me…" Mikey started to sob, he wasn't aware of even remembered because of his young age but he can imagine the scene well.

"I wanted a toy. I can feel that. I assume we were in the sewers. Don probably is trying to heal you and you gave me this." He puts down the origami flower. The petals had orange and blue color. "Before you…"

"I know you loved Karai, our enemy. The one who is in your haiku."

"And so, that's how you died." Mikey said. Absolute silence surrounded them and Leo clapped his hands, smiling.

"Good job." He said. "But you forgot one thing and one mistake."

"You forgot one thing. "How" did I die? You did tell the story behind... You forgot the question itself… How did I died, Mikey?"

The orange turtle just hung his mouth. Yup, he is supposed to ask Donatello about it!

"… You got shot?" he shyly said.

Leo shook his head.

"I'm sorry, Mikey. I won." The scar to Leo's arm disappeared. Mikey is shocked, he got this so well. He felt it's a terrible loss and a little upsetting. Mikey knew what Leo wanted if he wins.

"Well, go on."

"Go on what?"

"Take my soul already!" Mikey shouted. Leo has never seen Mikey this livid. He knew Mikey hated losing as he knew Mikey is a good observer when he worked on it. He is intelligent in his own way. He is able to solve this case even with little clues.

But by the look of it, Leo really felt offended and misunderstood.

"Mikey, I just want to borrow your soul." Leo said with obvious upset on his face."Even though I love you so much, I can't take your happiness with our family. My conscience will not take it." He looked away. "I just wanted to borrow your soul so I can feel you and you can feel me." Leo said as he tried holding Mikey's hands but they only get through.

Mikey just stared at him. He started to feel guilt and he didn't know Leo is this miserable in his state.

"The deal's off."

"Leo!"

And he disappeared.

Leo smiled at his two brothers are finally together. He knew Donnie had the hots for Raph way before.

Raph shivered and Don looked curiously. "Something wrong?"

Raph looked around. "Leo… I know you're here."

The computer suddenly opened and opened Notepad. As usual, the two brothers shrieked like earlier.

Leo smirked as he enjoyed the look of their faces.

FINALLY. I WAITED TOO LONG FOR THIS.

"Yeah, right." Raph said. "You knew this whole thing, right?"

YES.

"Seriously, Leo, you got to stop surprising us!" Donnie exclaimed.

SORRY. PART OF THE NINJA PACKAGE. IT ADDS EFFECT WHEN YOU'RE A GHOST AND YOU GOT TO EASE THE COFFEE, DON.

"A poltergeist, Leo." Donnie corrected.

"So how's you and Mikey?" Raph asked. They waited for a few seconds before the spirit typed.

IT'S FINE.

"Donnie, go to Mikey." Raph said.

"Huh?"

"Just go. I'll talk to Fearless." He said as Donnie went ahead.

Donnie knocked and opened the door. "Mikey?" He heard a sniffle. Something had happened.

"Mikey…"

"Go away, Donnie." He said, hiccupping.

"No, Mikey. I'm not going to ask you anything. I'll just sit here." He said. "Raph's orders." He continued before Mikey protested.

"Even though I can't see you, Fearless, I can tell something was up. Talk. I mean, type."

YOU WILL NOT UNDERSTAND.

"Try me." He crossed his arms. "Start typing."

Only sobs are heard in the cheery room of Michelangelo. Don just sat there, reading a book about spirits.

"I made him upset."

"To what?"

"I know he wanted my soul in the beginning." Mikey said. Donnie just stared at him. As a scientist, this is a laughable statement. But the fact that their brother is roaming around as a spiritual energy and Mikey is able to see and hear him but they aren't makes it a serious matter.

"Mikey, as much as Leo loves you, I've known his personality. He is not a forceful person in nature."

"I know my mistake alright?!"

"I understand you pretty well." Raph said. "I always wanted Donnie's touch." He said with a flush on his face. "Mikey is just cautious… Or scared."

WHY IS HE SCARED AT ME? I'M HIS BROTHER!

"Yeah but you're spirit, Leo. Don't you remember he was scared of those things? Leo, you had extra more powers than us."

"Mikey, if you trust Leo, he had his word. He never breaks any promises." Donnie said.

"I know, he's an honor dude, I get it." Mikey said as he hugged his pillow.

YOU'RE OKAY WITH THIS? WHAT IF I BETRAY YOU BECAUSE I'M A SPIRIT?

"Poltergeist." Raph said as he groaned that he got Don's habit. "And you won't. You're too noble for that. But just to make sure, if you double cross, I'll exorcise you."

DO YOU EVEN KNOW EXORCISM?

"I watched a lot of horror movies." He said. "Do something funny and I'll be Dean Winchester in your ass."

NOTED.

"I'm scared, Donnie." Mikey said.

"You know, Mikey, when you're with Leo, you will feel you're safe. He proved that during the missions when he was still alive. Think of Leo now… As Casper."

Mikey laughed and muttered. "Yeah, right. Leo is indeed a friendly ghost… Too much friendly."

The door opened, revealing to be Raphael and through Mikey's eyes, Leo. The ghost knelt in front of Mikey.

"I'm sorry…" Leo said and breathed deeply. "I'm sorry I scared you… Please forget about the bet. I'm alright with it."

"Leo… Yes."

The poltergeist looked up. "What?"

"I agree for you to temporarily take my soul."

P. Leo might took a little break for a while as my brain had too much info. and had to take a maintenance XD
Mikey is intelligent, really, but in my head he tend to drift from the actual mission XD For me, Mikey had the most potential and it shows when he really "worked" on it.

Yes, I had a headcanon Raph watches Supernatural.
