Charlotte - Yuu Otosaka Character Discussion

I’ve been meaning to ask this, and I’ve been curious as to whether it was because of bad scripting, or not remembering things, but.

In episode 13, if I remember correctly, people were trying to shoot Yuu, but Yuu was blocking it with a self-shield. If I remember correctly, he was sleeping for part of it while people were shooting at him, yet the shield was protecting him. Does that mean that the shield protects him whether he’s sleeping or awake ? Cause later in the episode, he gets shot using another weapon (sorry. Not a big fan of remembering weapons), by a man later on, and the shield doesn’t protect him anymore. Was this just bad scripting, or was the shield only bulletproof ?

In episode 13, someone controlled him, maybe an inner thought or a dead person, and who could that have been ? I was always curious because that scene could have been a good starting for a second season if it was planned.

Yuu looses all his memories in the end. Does he still have his powers and abilities ? I doubt that powers just disappears when you loose your memories.

Is it possible that Yuu was possessed in episode 13 throughout the scenes, such as when he was dragging people in the desert and such ?

Is it possible that the Yuu we see at the ending is actually someone else who’s possessing him if he still has his powers ? When he fell asleep, someone was possessing him and burnt the whole room. What are the laws when he passes out ? This could have been some kind-hearted soul (literally) who followed Yuu around and possessed him whenever he saw Yuu throw the note cards away or ruin it, so he would pick it back up.

Why didn’t Yuu heal his eye ? He could have freaken time traveled and plunder that knife-chan little girl, sheesh.

This regards to Yuu’s powers, but isn’t it possible to save dead people using his healing powers ?

The fact that he had the power of a “medium” brings up a lot of questions that I’m curious about.
