Alternate Reality

When I finally opened my eyes I found myself in a dark room. The only light source in the room was coming from a computer. Where was I? The last thing I remembered was regaining the Death Note; I was with L, then….that light which struck us. That light did it transport me here? "Hyuk hyuk hyuk...well hello there Light." That voice it could only belong to "Ryuk, care to explain what is going on?" I asked. "Actually you have been transported to another reality. One where L plays your part as in he is Light Yagami's equivalent. As for you, you play L's part. I came here because it was my Death Note you initially picked up. I don't know why but there seem to be two Death Notes, the one from this world and mine." He said "But if there are two Death Notes, there should be two shinigamis or you should have swapped places with someone." "No Light, shinigamis are constant, I can tell you this though. My Death Note belongs to you, the other is for L. But it's with me. I thought I should consult you on what to do with it since your ideas are always interesting."

All right so from what Ryuk told me it seems that I am this world's L. Also I have both the Death Notes. "Hey Ryuk, how do we get back?"

"Well that Light I can't tell you."

"Can't tell or won't tell?"

"Both… I can't tell you that right now actually."

"I see. Ryuk, if I manage to kill L here, in this world, would that mean he would die in the other world as well?"

"That's right."

Wow I never thought being transported to an alternate dimension would give me an opportunity to kill L. Wait a minute if L figures out that we swapped positions he would obviously try to find the other L, who is Kira. So what exactly is my best option here?

"Hey Ryuk if L gets my Death Note, I mean the one from our world can I still control it?"

"That depends, since that Death Note is not meant for him, you won't have full power over it though, I would."

"Well if I give L this world's Death Note, can you borrow it and give it to me so I can kill somebody with it?"

"…. would mean you would be its holder until L kills someone using the same Death Note again."

"That's all I need to know now. Wait; do you know where L is now?"

"Yeah I saw where both of you were transported."

"Great. Now could you do me a favour and give this Death Note to L, exactly the same way you gave it to me."

"Fine, I have a feeling things are going to get interesting again Light."

If my plan works I can easily kill L anytime I want. Also I can use him as a decoy while I do my duty as Kira.
