Fairy Tail 317: Future Lucy is lying?

Recap and Comments of Fairy Tail Chapter 317: Lucy and Natsu

Future Lucy has finally told to Natsu and his group that a herd of 10000 dragons is approaching. Naturally they freak out a little bit.

Carla had a flashback concerning sorrow just before Daimatou Enbu and now she understands what that is about. She then asks Future Lucy what happened to them and she implies that Natsu and everyone dies.

Future Lucy begins telling about the eclipse, how she somehow managed to open the gate and that she accidentally managed to come to the past on the 4th July of X793, which was few days ago.

She wants to meet Jellal and the others, since she told him everything and that Jellal should be thinking of a strategy.

We get Archadios' flashback of princess saying that there's another way to use eclipse: Eclipse 2. Princess says to him that the magic has reached about the same power as etherion, which is the powerful weapon possessed by Magic Council.

Archadious knows that Future Lucy told the princess about Eclipse 2 and that she lied about her coming on the 4th.
What reason does he have lying to Natsu and others? I believe that as she knows what will happen she doesn't have any bad intentions. I believe that her lying is her thinking that if she'd told the truth it would make a unwanted reaction especially in Natsu. So in the end this is a trick used by Hiro Mashima since now readers get a feeling that there's something evil about Lucy at this point but the solution to this may be just what I speculated.

 Natsu comforts her thanking her for protecting their future and they will definitely change it.

Somewhere outside the city Ultear, Jellal and Meredy are talking, they speculate whether what Future Lucy said is true. Jellal come to conclusion that either what Lucy says is false or Lucy herself is a fake.
This is a powerful way to create doubt in the readers, but I stand behind my theory ;). 

Meanwhile at Daimatou Enbu Gajeel has overpowered Rogue who's panting on the ground. Rogue starts telling him how he admired Gajeel in Phantom Lord and that he knows how Gajeel joined Fairy Tail because of their friendship. Sabertooth doesn't have that consept, they were more like a army in which orders are absolute. Gajeel "comforts" Rogue by saying that at least Frosch (exceed) is his friend, and he's right.

Suddenly Rogue hears a voice which is saying that the enemy is still in front of him. It's saying that Rogue should kill Gajeel. He's seeking for the source of the voice and realizes that it's his shadow which is speaking, that is to say it's his Shadow dragon's power. It's saying that it will lend him power to kill Gajeel.

It was a good chapter, the doubt with the Future Lucy lying is a good twist to the plot, which I earlier speculated may just be a diversion created by Mashima. We still don't know the reason why she is lying but I think that if Future Lucy herself isn't fake then I think she has good intentions for lying.

At the end it was a interesting consept of Rogues shadow dragon power coming "alive" and speaking to him like to a paranoid schizophrenic. Of course this means that Rogue will have serious powerup due to his shadow lending him power, but at what cost? In chapter 318 we see Gajeel versus Rogue, which will be a interesting battle to see. Of course we still have Laxus vs. Orga vs. Jura, Erza vs. Minerva etc. Which I'll be eagerly waiting.
