Well, lets put this bluntly. He's insane. Thoroughly, violently insane. There's a bit of a story (really small, I haven't thought it through completely.). He was in love, really really in love with the young lady in the portrait beside him. She loved him, they were soulmates. Everything was all surgar and honey (I've got some strange sayings), until she was poisoned. She, of course, died, and that of course made him upset. He had three brothers, the youngest was next to die, then second youngest died, and he barely escaped. As things turned out, insanity ran in the family and the oldest was arranging these 'accidents' (where was the father? I just don't know. Off gallevanting with some of his friends through the country side or something.) for some unknown reason. He (blue hair boy) never found it out because he killed his oldest brother before he did. Unfortunately he was caught with 'red hands' and was blamed for the murders. His mother was all depressed, and he got locked up in a solitary cell for thirty years, and after about 25 of those 30 years he went utterly insane and killed all the gaurds in some unexplainable manner (small detail). Apparently I like angst.
It turned out okay, I think.
P.S. He loves that painting, it was done just before his wedding with his bride-to-be.
P.P.S. He has cool magical powers and is now immortal. Is it a curse or a blessing. I'd think curse in his case. And anyone who meets him.
P.P.P.S He has nice muscles.
I'll stop now.
