{ Zeref is silent for several seconds, trying to recall his few interactions with Gray in this world to the surface. They didn't talk much, of course; not as much as Zeref had with Erza, Lucy, Mirajane, and especially not Mavis, but for the most part, Gray restrained himself. Perhaps it was Mavis' influence, or perhaps Gray was actually using his brain for once, but whatever the case, Zeref was grateful that his interactions with Fairy Tail in this world have been mercifully peaceful if tense on occasion. }

Gray was in this world for a while. I don't think he ever told me which timeline he was from, but he behaved about as well as anybody could have hoped. I suspect Mavis had something to do with that, or perhaps Silver did, but I never asked.
