Episode 16, a lot of political play in this episode. For the most part, it's calm before the shit storm!
[spoiler]Now there are reports of the Emperor going missing. With that Zero proceeded in finalizing his alliance with other nations and declared war against Brittannia and liberate Japan. And then under Zero's nose, the Emperor hacked into the worldwide broadcast declaring that he'll accept the challenge.
With the Emperor now back, Lelouch is now extremely worried about Nunnally safety to a point he accidentally took out his frustration onto C.C. As he quickly realized what he has done, he quickly came to her aid. C.C. mentioned that getting external wounds are better than getting internal ones. Lelouch then asked he how does she deal with them, and she replied that asking for friends works. It is that moment Lelouch decided to call up Suzaku so he can protect Nunnally. But before Suzaku can do that, he wanted to talk to Lelouch alone.[/spoiler]
A lot of moments in which I'll more likely going to skim through.
-
Bwahahaha, hell yes!!!
[spoiler]- That Knight 10 is a real jerk.
- Nina wants to implement her new onto Suzaku's Lancelot. Damn, talk about one gigantic responsibility on your shoulders.
- OH GOD, C.C.!!!! YOU'RE SO MOE!!!! Even with her memories shifted back to her slave days, she still loves her pizza! >_<
- Speaking of memories, Anya's memories seemed to have been altered. I wonder why.
-
Symbolism, anyone? 
[/spoiler]
On the most part, I noticed death flags and betrayal flags raising a lot in this episode.
