well, he absolutely has to be the main for the first, but the second is more his friends book, but the third he is incredably important. as are a wealth of side characters.
i guess he just feels a bit bland to me when he isnt blowing things up. for example, there is a part where a friend of his is killed, so he decides to pull a harry but worse, way worse. i mean blowing monuments worse
i have devopled him a litte bit since i put up this thread, but not a lot, he is just offically a smart ass. i have been rewriting a lot of things, for example i am making the conflict for personal to him, and giving him a reason he is doing it. but still, i guess i will have to put a lot of time into him, and ask myself questions, like what you said
