Etherion in Rave was no "ass pull power". That power was in the story from the very beginning... was the reason why the story could even happen in the first place, as we later found out.

It is absolutely integral and certainly didn't come out of nowhere in the scene you mentioned, so I at least do not count it as an ass pull.
