Charle and Happy then discuss Gray and the possibility of him being a fake. Happy says that he noticed something different but he couldn’t remember what, until he saw Gray stripping and states that the person fighting Natsu must be the real Gray. Natsu then angrily asks Gray if he's really going for it. Gray then uses his Ice Make: Battle Axe, but Natsu blocked it with Roar of the Fire Dragon. The collision of the two attacks causes a fog to appear and Gray emerges from the fog and kicks Natsu. Daphne then states that, the Gray that Natsu is fighting is the real Gray. Daphne then states that she isn't using magic to control Gray and that he's doing this of his own free will, to which Natsu replies that she doesn’t have to tell him that, because no one's punches can piss him off on the same way that Gray's do. Natsu then strikes Gray with Talons of the Fire Dragon, which sent Gray flying through a wall and their fight continues on the hall. Natsu then asks Gray why he's attacking, to which Gray responds “a city without sound.” Natsu states that he doesn't understand what Gray’s trying to say to him, but Gray says that Natsu doesn't understand it and that it doesn't matter anyway. Happy then says that both of their powers are about equal. Charle then states that this isn't the time to be impressed. Wendy then questions why Gray is attacking Natsu, and Daphne appears saying that he volunteered to assist her of his own will. Daphne then says that she came to Magnolia 10 days ago to investigate the origins of Natsu and then she happened upon Gray, who was interested in Daphne's story and decided to assist her. She then continues that Gray is her partner and a complete traitor. Charle then states that Gray is a complete traitor, but Wendy cannot believe it. Happy then comes to the conclusion that Daphne likes Gray which Daphne says that it could be. Happy then says Juvia won't let this stand. Wendy then wonders why Gray was saying "City without Sound" and asks Daphne why she is investigating Natsu. She then says that Wendy must hold all the questions for later and asks her if she wants to have some snack. Charle then says that it isn't the right time to eat but the food that Daphne is always seen eating. Despite Charle’s opposition Happy eats it and discovers it is spicy. Daphne then asks Wendy if she wants some, but Wendy declines and wonders if something is wrong with Daphne.

The battle between Natsu and Gray then continues, and meanwhile at the Fairy Tail Guild, Erza is wondering what Natsu is doing because he should have returned already. Lucy then says that he only went to ask about the dragons. Someone tells Erza to calm down, and someone else says that Natsu is taking his time. Mirajane then says that Natsu has Wendy with him and that it is strange for him to be late. Elfman is upset that Natsu is dragging Wendy around the town all night. Erza then says that she's worried about that thing that had attacked her today and wonders if that thing also has attacked Natsu and Wendy. Juvia then says that she's worried about Gray. The others were saying that Juvia is worrying too much and that Gray is ahead straight home. Juvia then angrily states that the intuition of a woman in love is never wrong. Erza then says that she will look for them and ask Lucy to come. Juvia and Elfman also want to search for Natsu and the others but Erza says that they must stay at the Fairy Tail Guild because she don't want to have the guild short-handed.

Mirajane then tells Lucy and Erza to be careful. The two then head off to find Natsu and the others, while in the Guild, for some reason Gajeel has a vicious look on his face.

Natsu charges over to gray and uses Flaming Elbow of the Fire Dragon and fell into a pool. Gray sees it as an opportunity and uses his Ice-Make: Prison to trap Natsu. Gray then stands on the cage Natsu is trapped in an taunts him, until Natsu uses his Roar of the Dragon technique to break out cage which causes a blinding fog to appear, Gray then appeared behind him and used his Ice-Make Lance technique.

Wendy says that she must stop the two of them with her Roar of the Sky Dragon, but Charle rejects the idea stating that she will hurt everyone if she activates it.

Happy then goes over to a window in an attempt to get help, but Wendy says that it is useless because they are trapped. Daphne then appears saying that resistance is futile and that means that they cannot escape, and Happy then decides to try to defeat her but he is attacked with her vegetable sticks.

Lucy asks Virgo to help Erza, but Virgo tells Lucy to be careful because the attackers use the same magic as her.
