It was a peaceful day in the layer I was meditating next to Master Splinter when I hear a big explosion and a pitiful screech from Donnie. I jumped a little and Master Splinter must have noticed because he placed a reassuring hand on my shoulder and looked into my eyes. I knew his expression told me to go check what happened. So I excuse myself from the dojo, and walked into the big living area.

"Donnie what the shell did you do now." snarled Raph as he walked into the same room from his bedroom.

"Well I may or may not have just created a portal that I don't know where it leads to." Donnie replied.

"Oh, Oh can we try it out D can we?" insisted Mickey out of nowhere.

"Remember last time we went into a unknown portal, we found a weird krang place." I recall.

"Yea, yea I know Leo but come on you know you want to see where it leads." insists Donnie. I pause to think, yea part of me is telling me what the heck let's go see. The other half is telling me it's a bad idea.

"But what about Master Splinter?" Raph puts in.

"What if we find another talking rat and introduce it to Splinter. Then he would be too busy with his new friend to notice that we are gone." thinks Mickey. I just face palm and Donnie tells Mickey how unrealistic that could be. Raph just hits him in the head."Oww come on that was a good idea!" shouts Mickey.

"If it was a good idea I would not have hit you!" growled Raph.

"What's all the commotion about my sons?" asks someone from behind us.

"Master Splinter!" we all screech. We just stand there like some deers in headlights.

"Does anyone want to tell me what's going on?" asks Master Splinter. We all just stand in silence.

Then Mickey says, "Something we want to tell you, no."

"Leonardo what is going on here?" master Splinter insists. He just glances at me but I feel that I have so much guilt that it's tearing me apart.

"W..well we um… Donnie kind of built a p..portal." I stutter.

"Donatello how many times do I need to tell you not to build such dangerous things!" scolded master Splinter.

"I'm sorry Master Splinter." mumbled Donnie.

"Good now please take apart that portal before anyone of your brothers get hurt." exclaimed Master Splinter.

"High sensei." grumbles Donnie. Then Master Splinter leaves the room.

"What the shell is wrong with you Leo!" curses Raph.

"W..what did I do?!" I question.

"You know exactly what you did!" growls Raph.

"Come on Raph its ok we all know Leo can't lie to Sensei." insists Donnie.

"Yea some fearless leader." mumbles Raph. Then Raph leaves to go to his room. I stare at Donnie but he has his eyes to the ground. Then don starts making his way to the lab. I feel horrible about it but I can't lie it's not in my nature. Then Mickey pats me on the shoulder.

"Come on Leo let's watch that Space Hero show you always watch." grins Mickey."Oh and I can make my famous jelly pickled popcorn!" Mickey said happily as he bounces off to the kitchen. I walk over to the couch and sit down in the middle seat. I then turn on the TV and change to the channel that always shows Space heroes. Today's episode gave me an idea. Captain Ryan had messed up one of his crewmate's favorite chair so he went and fixed it by himself. I know I can't build anything like Donnie can but I can fix what I've done. So I tell Mickey he can eat all the popcorn he made and then I rush into the lab.

"Donnie?" I ask. There is no answer. "Hey Donnie where are you I need to talk to you?" I ask again. Still no answer so I start to walk around the lab. I walk up to the weird portal Donnie had built. "This is pretty cool." I say out loud.

"Yea I know so we are going in it." Someone exclaimed from behind me. I turn around to see Donnie, Mickey, and Raph.

"Why the shell do we have to bring Leo he will just tell on us." barked Raph.

"Well he is are leader." insisted Donnie.

"HEY." I shout. "What is this all about I thought Sensei said we could not go into the portal!"

"Sensei never said we could not go in it he said to take it down and make sure no one gets hurt." explains Donnie.

"So as long as we are safe we can go." laughs Mickey.

"But we don't know where that portal leads to." I exclaimed.

"That's not all true my calculations say that this portal will lead us to a lovely forest that is safe." replied Donnie.

"But still, what about Sensei orders?" I ask.

"Is the great fearless leader scared to go into the portal?" mocks Raph.

"I am not scared!" I shout.

"Then prove it." Raph sneered.

"Fine I will, come on guys let's go." I exclaimed. Then we all go through the portal. We end up on the surface in an alleyway but things look different. There is more scum, and trash and it does not look very pleasant.

"Donnie I thought you said we were going to a forest." Mickey said disappointed. Donnie pulls out a little device.

"Donnie what's that?" I ask.

"It's a little gadget I wiped up for this portal it tells us where we are." replies Donnie.

"But we already know where we are, we are on the surface." points out Mickey.

"It looks that way but if you look around doesn't it look different somehow?" questions Donnie.

"We still don't get what the shell you're concluding to Donnie." said Raph.

"I'm saying that even though it may look like we have only just teleported to the surface, we might be in an alternate universe." explains Donnie. We all just stand and stare in silence. Alternate universe hmm, I remember Donnie told us about them before they are usually a world similar to ours but are different in some ways.

"So what kind of Alternate universe are we in?" questions Mickey.

"I don't know." response Donnie. Just then we all hear a noise of running feet close by. It's too late for us to respond and when the person runs into the alleyway it shocks us all. A girl with long black hair with a mask and hockey sticks on comes running into the alleyway. She looks just like…. CASEY!
