User blog comment:Miskos3/Fairy Tail Episode 245: Tartaros arc: Hell's Core, Review/@comment-26416024-20150808160529

Remember that tweet by Mashima saying there was going to be new stuff added to the Tartaros arc in the anime that he wanted to put in the manga but was not able to for one reason or another. Could the events of the next episode be what he was talking about?
