User blog comment:R. Lawton/How strong are some the GMG characters in comparison to Fairy Tail/@comment-3290324-20130910235608/@comment-7418318-20130911002253

Not only did she feel no pain, but she didn't have those red symbols all over her body either, like all the others who's second origin was released.

This gives a bit of credibility to the theories of Erza having her second origin even before Ultear tried to unlock it.

I fear this is one of the things we'll never know for sure, unless it's answered in a Q&A or an interview.
