Well, if Mest was here, they could just send Gray and Mest to get him back. But Mest has been missing for quite some time (I guess he collaborating with CrimeS, the perfect job for him, or searching for Gildarts, who hasn't even been mentioned, unlike CrimeS), so I guess Gray and Jet could try and bring Natsu back? It'd definitely make a useless character somewhat useful...
