99% sure the real Assange is dead.

The last video I saw of him "alive" he acted almost non-human stuck behind a small window in what seemed like a hyperbolic chamber. He just kept up this really creepy smile with darting eyes. (Props to you if you have that video.)

I think it was a mask of some sort and he didn't open his mouth because it would risk having the mask slip.

I have no allusions to his safety. Be prepared to hear he's been dead for 4 years at least.
