some hints were already given by Mashima about the future, if you remember :

1. the spirit directly connected to Layla appeared during Tenrou arc and was with Grimmoire, and who appeared during this arc : Zeref and Hades 2. It was said Zeref came from the east, so maybe there is something here that can help the magic wolrd in the case Face is activated 3. why and how Layla knew the one magic, but Makarov didn't 4. Where Layla came from, i doubt Layla was just a mage who worked in Love & Lucky, there is something else
