I've increasingly come to believe that Captain Flint and Aemond Targaryen have so many strong parallels. They are both extremely tender and vulnerable on the inside, but absolutely bulletproof, stern and explosive on the outside. Both bear an open, constantly bleeding wound in their hearts. Both are without equal in how far they are willing to go for the sake of their goal or their revenge. But the most interesting thing is that both of these characters have enormous potential of doing good works. Only the pain caused to both of them turned out to be so great it has just about blocked all that is good in them completely. Both Aemond and Flint had gotten burned so badly that later they are almost unable to deviate from the path they took because of it, because of this old burn wound.
