User blog comment:Miskos3/Fairy Tail Chapter 318: Gajeel vs. Rogue, Review/@comment-5201441-20130207150824

I thought Gajeel got really badass.

For me, him eating the shadow was better so it's not only a Natsu power-up, but a Dragonslayer thing.

The speech o "Shadow" made me reinforce my "theory".

Future Lucy is a true one, but she is/was possessed by some unknown entity.

As the others felt it, I'm thinking that Shadow was in Future Lucy, but now, to ensure the results of the Games go as he told the Princess it was going to happen, he possessed Rogue to make it happen.

Let's see what happens next week.
