Fairy Tail Episode 252 English Dubbed Episode Title:Tartaros Chapter – Gray vs. Silver.Episode Description:Gray furiously attacks Silver, whose Ice Demon Slayer powers make him immune to Gray's ice magic. Gray tries channeling Silver's magic against him as previously done against Doriath, but it also has no effect. With no other options, Gray contemplates using the same Iced Shell technique used by Ur to permanently freeze Deliora, despite needing to sacrifice his own body in order to do so. He reconsiders and ultimately grievously wounds Silver by hurling a cannonball through his chest. Gray refuses to kill Silver, however, reasoning that he is not Deliora as he claims to be.
