Speaking of animes trying to right themselves, I've been wondering... Somewhere in the beginning of Season 2, there was this episode where they returned to the dimension in which earlier on, Sakura's wish at a temple had brought life back to a bunch of people who had died in trying to make their wishes come true. In returning, the gang discovered that these very people where about to die again, and in the end, there was nothing that could be done to prevent it.
This "correcting" episode, was it demanded by CLAMP since it violates one of their rules, or did Beetrain take the initiative themselves when they discovered the misstake?
