Okay. So here is my modern AU of Mairon meeting with the normal Mairon. (And the regular Mairon will be called Sauron so not to confuse anyone)

Sauron: So. Let me get this stright. You are from a world where Eru, the silmarils, and everything I know dose not exist. But, the people do and in this world you are me?

Mairon: *nods* about right.

Sauron: and in this world you are roommates with Melkor? Where you have to pay to keep your home and everything working, you also have to work, clean, cook, and make sure that you have supplies to live. Where Melkor has no job, sits around and dose nothing?

Mairon: Yep.

Sauron: *sighs* I feel your pain. My Melkor just tries to fight everything and everyone and ignores logic.

Mairon: at least he has no wifi connection and can bit get sick.

Sauron: you has to deal with a sick Melkor?

Mairon: At times I wonder if am his roommate or his mother.

Sauron: *shakes his head* I pity you.

Mairon: it's fine. I have ways of handling him.

Sauron: how?

Mairon: a spray bottle with water and changing the wifi password. Both cruel but they work and I must do what I have too.

Sauron: I think you have a harder time then me.

Mairon: Most likely. *gets text message from Melkor* *it reads: Where are my socks? Why don't I have socks?* *Mairon turns off phone and sighs deeply* I am pretty sure he'll die without me.

Sauron: Both of ours will.

Mairon: *rubs his head* how about a trade? I deal with your issues and you deal with mine?

Sauron: I am tempted to say yes but I maybe wise for us to sick to issues we know how to deal with.

Mairon: that's understandable. *gets another text from Melkor saying they are out of Corn Flakes* I have to go and kill my roommate. It was nice talking to someone who understands my issues.

Sauron: like wise.

*Mairon leaves*

Morgoth: *walks over to Sauron* I can't find my socks...
