Mance Rayder is the son of Bloodraven.

Nice! I had missed that in the text but was just thinking it. See above. LOL I think as either son or grandson it's pretty clear that Mance has Targ blood.

Mance could be called unburnt as well. "He" was given to the flames but sits at WF unharmed by them.

shymaid , nice tie with Mance noted to be the "unburnt king", which is something I have never picked out of the text, but have wondered what might have happened had he actually burned in that cage.

Perhaps it is because Jon thinks about his burned fingers so often after the initial fire. Some of my thoughts are related to the finger flexing that he does that goes right up to the time of his stabbing, four books after his initial injury. (However, I am not convinced that finger flexing is all about his burns and more a learned or genetic behavior-that's a whole other pile of sticky notes trying to form into a theory).

But Jon receives his burns in Game, Jon VII and he talks about his burns in great detail in Jon VIII, and then again in Jon IX we hear that Jon has his wrappings off but they still ache and burn and pain him. I am not sure how long it's been since the burns occurred but it seems like even though Jon reports that the fingers are scarred, he still feels more than a little pain. In Clash, Jon II we hear that Jon is taking off his gloves and letting the fresh air sooth his burned fingers, he thinks of it as "airing his burned fingers", which is rather vague and I doubt there are still open wounds on the skin, but it's an odd thing to say. At this point it has to be several months since his burns, and they should be past the initial stages of healing. In Clash Jon VI, when Jon is climbing the pass in the Frostfangs, he complains of his "burned" hand aching and stiffening up. I would think that both hands would feel equally bad from all the mountain climbing but it's only the burned hand that Jon mentions.

Granted, this could be misunderstanding what is in the text and how GRRM wants us to almost fixate on Jon's burned fingers, since the author has Jon fixated on those burns. Perhaps they are healed and Jon is just fixated on them, but months later when he is letting the air sooth his fingers, that seems more than a bit odd to me. From my first read of the series, I was stuck by Jon's burns and how (in my head canon, at least) that his hand and fingers seem to take a long time to heal. Of course, my head canon could just be incorrect! I have also been struck by the things that Jon reports soothed his burns, which are ice and water, snow, cool air. All things of the north that seem to sooth the burns that fire caused! Jon is off the north and soothed by things of the north!
