Dick hate Bruce Wayne persona. The playboy billionaire that he shows in parties. He know it's for the greater good but it is still utterly disgusting to see.
He hates the women that latch on him, thinking they're a snake or something. They're not even that flexible and their make up could rival the joker.
Dick hate it when Bruce decided to bring one home. Maybe this is his training for Dick to have the patient of a Saint or the skill of avoiding people. Well it works.
He think its funny, how they think that Bruce has infinite love for them thus enabled them to use him but of course Bruce doesn't and he's only doing it so that people can't relate him to Batman. Hidden behind a mask during the day and night.
Batman himself is the opposite contrast of Bruce Wayne. Lot more tougher, a lot more intelligent and a lot more intimidating. It would be a dangerous decision to cross him and everyone knows that.
Dick used to think that his intimidation is part of this whole hero gig. It has proved itself to be useful dealing with demented criminals that Gotham do so favor.
Batman's core is already in Gotham. Where there seems to be an endless blanket of cruelty and darkness. Batman's only different is, well he's the goddamn Batman.
Dick's core is in the heart of the circus. Where there seems to be an endless spectrum of colors. The only thing that is similar with Batman and him is well, What Gotham took from them.
So Dick Grayson became a somewhat feng shui. Enough optimistic but not too much to be naive. He tried to maintain that but its getting harder as he grew up, as he understand more darkness.
He hate 'Bruce Wayne' but he hate 'Batman' more. He doesn't want to become the Batman. Sure there was a time in his lifetime wanting to be one. The whole successor thing sit on his shoulder and he was proud of it. He would even sometimes borrow his cowl playing Batman. But it shift. What he's proud of became his burden. He look at the cowl like he look at his greatest fear. He wear the cowl with a sense of fear. But that's Batman isn't it? He became his fear, tackle it, use it whatever. Bruce became Batman because of his fear for bats now Dick fear that he has to. To reject the call of duty is somewhat an act of coward but Dick couldn't really care.
Dick wouldn't admit it but when Scarecrow use his fear gas on him that one time and he tried to run away from Batman because he was scared of him. Dick doesn't tell him cause he knows it would break him. He only told BC cause he just can't keep it in anymore. There just an ache in his heart to escape, to shout, to struggle because like it or not, he is the successor of the Dark Knight.
So he moved. He didn't move to Bludhaven just because he wants to go solo. He move to Bludhaven to escape his sealed faith.
