I really am having trouble understanding this whole "I'mma become a God" plan. First of all, they already stated that they could only get the vaccine out to Japan, not having the foothold in the rest of the world. Second, unless this plan is publicized, it won't do anything to protect the children that the various governments are already tracking. They won't know that these kids lost their abilities, and are still going to hunt them down. If it was publicized, Yuu is still gonna be super-hunted. My monies on him dying at the end.
The declaration of love between Yuu and Nao was just...way over the top and cheesy. We knew that those feelings were there, and the scene at the end of the episode alone would have been more than enough.
And the biggest plot issue I've had so far is that everyone, from the beginning of the show, has been super eager to give up their abilities/agree to stop using them. I could understand a few being alright, but if I had awesome unique super-powers, I'd probably consider them a large part of me and be really upset at losing them. Misa, though, that was painful
And HOW THE HECK is he going to plunder 1000's of people's abilities? Even if he has a Poo-like ability-wielder, he's already 16. It'd take years to hunt them down. That's less an issue with the show and more a question to be answered next week, though.
