The backstory for the Silver King and the Slate was very strange. The flashbacks are getting a bit annoying, not so much that they happen, but rather that they create more questions than answers imo.

So here's my theory. That spirit thing looked like a fox/cat. My guess is that it is Neko or another Strain creature at work. I would be surprised if it was Neko, as she is much more playful in her antics. This mysterious called was much more malevolent...threatening Mikoto via Anna (jerk! no one messes with Anna! I'd be full of rage too! XD)
