Honestly, I still think they're inside of Mavis...the one place where no one else can help given Zeref's looming frame of Trollishness

If Gajeel is indeed "dead" then his spirit is within Fairy Heart itself, which Zera (an apparition taking her appearance or whatever she is) lives within because Fairies live inside the hearts of people and specifically, Mavis' heart >.>

That's the best I got cause I have NO IDEA where the fuck Hiro plans to go with this
