[After Nao's finally caught up to the events, or as close as being caught up can be when he's still not sure how much he's absorbed (too many things happened and he didn't even see them, it's pretty worrisome), he finally manages to find the time to contact Rin. He feels kind of bad, after all, since he didn't mean to jinx himself and actually disappear.

So ring, ring, ring Rin.]
