Authors notes- I don't own the TMNT, only Karma and Yoshi.

Leo fans, forgive me? Please? –Hides-

Gosh, this story's had, um, well a lot of interest. I hope I don't screw this up.

Love hurts.

I stare at the turtle opposite me.

'Mom? I'm a… mom? No, I'm going to be a mom…?'

"… I… I'm very far from home aren't I?" With a saddened look I turn to Don.

"Looks like it…" He says quietly, eyes drifting to the ground.

As I turn around, Leo squares up to me.

"You shouldn't be here." He frowns.

"Sorry, I'll just go take on Drako and the Daimyo's son and get the Time Sceptre back shall I?!" I snap back, not liking his tone.

"What?" His brow furrows deeper.

"Never mind." I sigh. "All I know is I'm here, and will be for… well, I'm not sure how long for."

"We could fix up a De Lorean for you?" Mikey grins, and I can't help but smile.

"I've got a lot of questions."

"And you're not getting the answers." Leo folds his arms.

"Okay," I put my hands up in defense, "When did you turn into an asshole?"

Don and Mike recoil behind me.

"I'll pretend I didn't hear that." Leo lowers his voice and narrows his eyes.

Smirking, I fold my arms.

"I'm getting answers, whether you like it or not? Where's Raph?" I look around to my two other brothers.

"He's none of your concern."

I laugh slightly.

"I think he is Leo, where is he?"

"He doesn't live with us…"

"Mike." Leo snaps.

"She deserves to know!"

"She deserves to know nothing." The oldest brother hisses into his face.

"Leo-"

"This isn't her business!" Leo roars at Don.

Silence ensues.

"You seriously are being an asshole."

Leo spins on his heels to face me.

"I don't know who you think you are to come charging in here, and tell me what I'm doing is wrong! You don't have that right! Nobody does!"

"Except Master Splinter." I say calmly.

"Karm…" Don shakes his head at me sadly.

"I want you out of here when I come back." Leo says venomously and strides out of the Lair.

I let out a low whistle.

"What got into him?" I grin.

The three faces that look at me show three different expressions. Confusion, excitement, astonishment.

"You…" Donny starts, dumbfounded.

"Karmy." Mikey grins and hugs me tightly.

"Yeah Mikey, it's me." I stroke his shell, and as he pulls away, Yoshi looks to me.

"You're nothing like I know…" He seems to be struggling.

"Yeah, I'm younger than you for start." I grin, and Yoshi's walls finally come down. He returns the grin.

"So, who cares to tell me what the hell has happened?"

Donny shifts uncomfortably.

"I will… if I can sit." He winces.

Going over to my brother, I slip his free arm around my shoulders and guide him into the kitchen, Yoshi and Mikey following. I help Don sit carefully, then take my own seat.

"Dude, you look naked." Mikey grins at Yoshi.

"Huh?" He frowns, then realises. "Oh yeah." He pulls a green ninja mask from his belt and ties it into place.

"You really are my son…"

"Yeah." He smiles awkwardly.

"Mine and Raph's." I assume, giving a grin. "Say, where is Raph?"

The expressions change.

"We need to take this from the beginning…" Don sighs.

As Mikey starts to make coffee for his purple banded brother and myself, Don starts to talk.

"Raph… Raph doesn't live here, he hasn't for… 16 years… and you should know about sensei…"

"I think I already know…" My heart sinks. "Was… He… How?" I can only just say.

"Old age." Don smiles weakly. "I guess our only comfort."

I nod, understanding.

"That… that is a comfort." I hold back the tears, for Mikey's sake. "But Raph?"

"He'd had enough, he walked out on us, Leo was… he was upset."

"He doesn't seem it." I scoff.

"Think about it, Karm. Leo and Raph, they clash constantly. That clashing kept Leo level-headed I guess. Raph up and leaves, and… well, Leo has nobody to clash with. His anger gets pent up, he gets pent up, he starts to get… controlling."

My eyes widen.

"Wait a damn second… you should know me, I'd never let Leo get like that. He listens to me, he-"

"He loves you." Yoshi speaks.

I double take.

"Excuse me?" I peer at him.

"You two-" Don starts. "Wait, Karma, where you came from… who is your partner?"

"I'm with Raph." I frown.

"Why?"

"Why…?" I'm a little perplexed by the question. "Um, well, I liked Leo and Raph but… Raph." I smile at the memory. "Raph leapt off the Foot freighter to save me from drowning. I guess… I just kinda fell for him."

"Time and space…" Don mutters, then looks at me, wide eyed. "Karma… this isn't your future… this is an alternate reality. In this world, you exist, everything with Stockman happened, we rescued you from him, but something, some event, made everything turned out different."

"Wait, you're telling me, this is the alternate reality where I picked Leo over Raph?!" I turn my eyes to Yoshi. "Yoshi is mine and Leo's son, named after…"

"Sensei's sensei. Leo felt he owed Master Splinter that much." Mikey says, setting the coffee down on the table.

"It's not a when are you, it's a where are you…" Don looks at me. "Every action has it's consequence, every reaction has an opposite reaction. By choosing Raph, this alternate reality was created where you choose Leo."

"And this is how it ends up?!" I cry out. "If this is my alternate reality self's life, then where is she?"

"On holiday…" Mikey says quietly. "You and April are on holiday…"

"The Farmhouse…" I breathe.

"It became an annual thing."

"I need to find Raph." I stand up. "This needs to be fixed."

"No!" Don exclaims, "If you try to fix this so that you and Raph are together, that will disrupt everything! When you go back, it will change your world, because everything needs balance. Ultimately, Raph and you will break up, and you and Leo will get together."

"You're saying… you're saying I'm screwed?"

"Yes…" Don says dejectedly. "You can't help."

"No, you said I couldn't get Raph and I together, I'm not going to do that." I stand.

"Then what are you going to do?" My brother looks concerned.

"I'm going to put this family back together."

"But…"

"But nothing, Donatello." I look down at him. "This is obviously a very broken family, and I need to fix this-"

"Everything happens for a reason."

"And that's why I'm here." I wink at Don and turn to walk out the Lair.

"Wait!" Yoshi shouts out and I turn to him. "You don't know where Raph lives."

I smile weakly and nod. We head out into the sewer tunnels together.

Authors notes- Okay, I'm gunna be nice. This is an extremely confusing storyline, I know, so I'm gunna do something different. I'm going to let you all know where this is going, so, I'm swapping to Don's point of view. Enjoy.

I watch as she strides from the Lair, a swing in her hips and a determination in her eyes I've never seen in anyone before.

"She... She doesn't understand, does she?"

I shake my head at my brother.

"No."

"You should have told her!"

"Mike, would she have listened?" I look up into blue eyes.

"But Raph… he…" Mikey sits, head in his hands.

"I think I know how this happened." I announce.

"How?"

"The Butterfly Effect."

"What?"

"The Butterfly Effect, or the Chaos Theory as it's also known, states that one small thing can change huge things. The beat of a butterfly's wings can cause a tidal wave half way across the world, that kind of thing."

"So?" He looks at me, tiredly.

"I can only deduct that Raph, Leo or Karm did one small thing that changed their whole future, for better or worse."

"What Raph did to Stockman-"

"Way before that." I shake my head. "Leo and Karm fell in love way before that. Karm mentioned when Raph leapt from the freighter to stop her from drowning that was what made her fall for him."

"But that was Leo."

"In our world, it evidently was, but in Karm's world, the young Karm, it was Raph."

"So… something happened before that night?"

"Yeah, but I'm too old for this now Mike." I sigh. "I can't remember before that night so clearly."

"Karm will."

"She needs to talk to Raph first."

"Will he tell her?"

I stretch my left leg, wincing with the pain.

"Raph never has been a talker, Mike."

"Then we should tell her-"

I shake my head sadly.

"Karm needs to talk to Raph, as a comfort, just to see if he's okay. I know Raph won't tell her, he's too ashamed. He's not the Raph she knows, she'll pick up on it of course, but he won't tell her why. You know his story Mike."

I'm pretty sure Mike is remembering the story he was told by his older brother.

'I'm movin' out so ya can have space, yanno. I can look after myself Mikey, an' ya can always visit. I just don't expect it from Leo. I can't stand the guy! Heh. It's better this way, no more fights. I won't hurt anybody no more.'

Mike sighs bitterly.

"I won't hurt nobody no more… that's what he said." My younger brother's eyes fill with tears. "He hurt me Don, he lied to me."

"And he'll lie to Karm. He just wants to protect her, just like he wanted to protect you."

"He's a damn murderer, Don! That's not protecting me!"

"Mike-"

Michelangelo hastily exits and I sigh.

'Trust me Mike, it still hurts me too. Baxter Stockman was a cruel man, but he was a genius too. How Raph could ever think by killing him, that Karm would be grateful, I'll never know.' I think back bitterly. 'But none of us knew about Shinrai. Karm probably would have been grateful to have Stockman out of the picture, if it hadn't meant Shredder decided that as long as Stockman was dead, Shinrai was just a waste of space too…'

I rub my temples, trying to ease my headache away.

'But there's too much going on for me to sit here. This family has tried to bury things for too long, and Karm's right, something needs to be done.'
