User blog comment:Miskos3/Fairy Tail Episode 246: Tartaros arc: Underworld King, Review/@comment-4933386-20150815083954

After seeing Rusty tries to recreate the Grimore Heart with his magic made me feel so sorry for him... he's so lonely.. meredy certainly didn't make him feel better.

I really hope that this episode is canon and Rustyrose joins Crime Sorciere... as well as other members of the Grimore Heart...defect them all into fighting Zeref. They wouldn't put an entire episode in the middle of a major arc that is completely irrelevant. Idk maybe it's just me with high hopes.

Also, I think I liked this episode a lot because it doesn't focus on Natsu and Co. I wonder if the manga will ever make a spinoff based on them... We've seen Gray, Fairy Girls, Wendy, Sabertooth and Mavis(and the other people)...
