Well this was a bit of a twist. Never considered the fact that those who are "cured" in actuality just end up forgetting all about the person or thing that was the source of their psychological strain entirely. I guess if you don't remember it, then the mind can't stress over it.
Saya's definitely up to something though. If it wasn't for that little push she gave to Yomi then she probably wouldn't have mentally degraded as far as she did. Her motive is still very unclear at the moment.
Strength made her first appearance too, even if it was short. I'm not sure if her presence is very significant at all though. I guess we still have half the series left so maybe she'll be more prominent there.
With all this huge set-up I smell a very action-packed episode next week. BRS is gonna go up against Dead Master's entire army? That's bound to to be awesome.~
