Imo Mashima in character development has been very shaky, Gray including. The fact that in these past few fights he hasnt fought with strategy is already bad. Then the development with him and silver was truly lacking. Firstly, it was quite obvious that they were father and son. Then the whole "I'm Deliora" thing ended up being pointless because all it ended up doing was mess with Gray's mind before him just seeing through the guise. It really didnt help anyone. Now Gray is hell bent on killing a demon who has neither done anything wrong nor has really anything to do with any of the problems that have been caused all because silver was told a lie and passed down to his son. Now we find out that Silver has poisoned his son with demon darkness. His whole development with his father has been a roller coaster and a mess. Let me not even get me started with the development with Juvia. Basically she's some love puppet slave who almost sacrificed herself and her own guild for some deadbeat dad of her insensitive crush (it literally took forever for Gray to even factor in Juvia's feelings.) that she hardly knows. Now she is about to sacrifice herself again. The only development Gray has that actually went well is probably his friendship with Natsu and his acceptance of Ur's and Ultear's fate and that was a long time ago.
