In the part before the rite when we double jump the echo, o-app introduces us to Dunstan, and it's not within the Echo. It also seems he is wearing the same mask that will be used in the rite and that he actually will be present in the purifying rite of the present, not the past. But then we seem him participating in the past as well - so did the rite not work at that time? Khrimm was purified but Dunstan had to leave again?

And a bit before that it sounds like both Fye and Dunstan are still wandering the forest... @_@
