Hmm… Deidara and Hinata…keeping an ‘open’ mind… Lol. I can honestly say I’ve never considered this couple.
To those who know Deidara and Hinata as individuals, this relationship will probably be somewhat puzzling. Its foundation isn't always clear, even for its partners, should one ask them, they are often too busy giving structure to a family or purpose to be concerned with self-understanding. In fact, if the shared activity around which the relationship is built ends or falls apart, the partners may find little in the way of an emotional or spiritual bond to hold them together
Intimate relationships here, especially love affairs and friendships, might be the hardest to figure out. Intensely private, they may not be deliberately hidden from the world, but they aren't actively exposed either. They’ve been thrown together in the oddest and most unexpected circumstances probably necessary given the fact that they travel in such different circles, and have such mutually exclusive activities, that they might otherwise never have met. Yet they might have an immediate sympathy or fascination for each other, one that demands further interaction. The neglect of an existing relationship of some standing is often demanded here, increasing the level of tension, suspicion and mistrust all around. It may all be worth it, for, given the characters involved, it wouldn’t be a quick fling; it’s a serious, karmic relationship that must be thoroughly and laboriously worked through before it can be ended, one lifetime might not be enough.
DeiHina marriages would be enhanced by both partners' honesty and sense of tradition, but Deidara would find Hinata’s sometimes authoritarian attitudes oppressive (she was raised as the heir of a well-respected clan, and posses clan leader mentality, it’s hidden, but still there), both to himself and to their children(if they have any). Wisely, Deidara will rarely try to oppose Hinata need to ‘guide’ the ‘troubled soul’(lol), but in a subtle and diplomatic way he would seek his own areas of concern and control within the relationship. Problems can arise if Hinata‘s disapproval assumes an intolerant tone(she would try to impose her morals on him, the man essentially believes his art gives him the right to kill people, she would object, and he would think she’s being hypocritical, because as a kunoichi, she kills people too), for discrimination, or even small jokes or assumptions about others(and his art), has a negative effect on Deidara, and the relationship would begin to feature personal battles over intolerant and unaccepting attitudes.
