So what's up w/ the third eye on the forehead? How did it go away? What's exactly behind the mirror? Why are there less and less espers?

I'm not your type. I'm not inflatable.

Cry me a river, build me a bridge and get over it.

Everyone is entitled to be stupid but you're abusing the privilege.

Everyone has a photographic memory, some just don't have film.

The thing in the forehead appears as they use their power, so I guess it disappeared because he didn't really use it that much (maybe there is a point of no return, the main character just didn't pass it).

If you mean "outside the door" maybe it's some another dimension, who knows.

And the ammount of espers declining maybe it can be explained according to the family tree thing that appears in one of the chapters.
