User blog comment:FairyRaven/Fairy Tail Chapter 368: The Third Seal, Review and Commentary/@comment-7418318-20140129085343

I just thought of a crowning irony on Tartarus.

Not that I think it's even possible, but it would be so cool if either the council (during her "trial" after Lullaby) or Jellal (right before re-directing Etherion) would have transfered the seal over to Erza and now the sealer is sitting right under the Demon's noses. They'd be torturing the one they are looking for without even knowing it.
