[So basically, this video starts off staring at a wall. But if you think it's just any wall, you're WRONG.
It's a BLANK WALL.
And it continues to stream this same picture for a moment until something starts sliiiiding into the view. By the way, if you think it's Izaya, you're also wrong.
Instead, it's a full length mirror that, also eventually shown, is being shoved into place by this Orihara. Apparently satisfied with its new location, he grins and finally picks up the communication device. This makes the entire feed a little more obvious now.
Izaya is standing in his bathroom -- now between the mirror he just moved, and the mirror already on the wall. He finally speaks:]
Hey, so, I've can't stop thinking about those mirrors...has anyone else found some way to deter them or anything?
