The outcome for Iwasawa was clear from the very start of the episode, somehow.



Regarding the rest of the ep, I now see the world they are in as some kind of purgatory, where they need to vent their frustration for what they endured in thei lives, and accept their fate so that they can move on to their next incarnation.

But I find this explanation way too simplistic for it to be the one.

But the way they dissapear when they psychologically surrender, the very fact that angel is like them, seem to give credit to the idea.

Now for our Otonashi, should we be wary of him, or is it only a scenario trick that he looks a bit suspicious?
