I'm just going to pretend that Good Coop just started dreaming during the stand off at the sheriffs station. When he sees Naido, an image of Coops head appears on screen as he begins addressing everyone . From that point everything that happened was a dream.
Thanks. My head went into a spin when that started up...your post stopped the spinning...er, for now.
It's as good an explanation as any. Nothing that follows can be fully understood. Coop's "return" was short lived.
