OMG I wasn't this interested in a next episode since a really long time. Since the end of the Tenrou Arc I was curious what happened with the remnants of Grimoire Heart. And this is apparently some content that didn't made to the manga. We will see Rusty again, but wait, why is he attacking them? Also how come Azuma and Zancrow are there? Zancrow died and Azuma was turned into a tree by his magic. And where is that fat bum Kain? Rusty was the last person that saw Zeref after he left Tenrou and knows where he went, so I wonder if anything will come from CS meeting him.

My guess on Azuma and Zancrow is that they are created by the Arc of Embodiment, since the preview only mentions Rusty and those two look just like he remembered them. Which makes them Rusty imaginary friends, LOL. Still Rusty couldn't create life with his magic. Those beasts he made were more like soulless shells, that's why Bixslow could take control over them and destroy them. But if he can create living beings now that would be ridiculously overpowered.
