As a thank-you for saving Ermina, Mercphobia gives the group information on the rest of the Five Dragon Gods. And while they’re in the town of Tekka, they encounter someone who looks exactly like Erza...
With Natsu's fire, it might

Da kann Natsus Feuer sicher
wahre Wunder bewirken!
Con el fuego de Natsu
ganaremos fácilmente.
Com o fogo do Natsu,
deve ser moleza. Eu acho.
