code_geass ◾ ◾ Future episodes?

So today, I was looking at ANN's R2 episode page with

suruma, and the three next episode titles caught my eye:

2008-08-24 20. Emperor Disqualification
皇帝失格
2008-08-31 21. Connection of Ragnarok
ラグナレクの接続
2008-09-07 22. Emperor Lelouch
皇帝ルルーシュ

I, of course, was shocked at the Turn 22 name, so we looked up "Ragnarok" on Wikipedia, and got this:

In Norse mythology, Ragnarök (IPA: /rɑgnɑrɔk/, Old Norse "Final destiny of the gods"[2]) refers to a series of major events, including a great battle foretold to ultimately result in the death of a number of major figures (including the gods Odin, Thor, Freyr, Heimdall, and the jötunn Loki), the occurrence of various natural disasters, and the subsequent submersion of the world in water. Afterwards, the world resurfaces anew and fertile, the surviving gods meet, and the world is repopulated by two human survivors.

tl;dr: A major battle that results of the death of major figures, natural disasters and the world is flooded with water. Two human survivors eventually populate the world.

So, what does this mean for future episodes, or I am looking too deep into this? Is Sunrise going to screw us over with this?

Also, I'm not sure if I tagged this properly.
