Game of Thrones Bran with cold hands

Bran stays north of the wall freezing to death.  He looks at his hands realizing he may loose them.  Gangrene may beset them soon if he cannot find the warmth his body needs. The third eye raven may be lost and then what will become of the world of man?  Well we do know unfortunately.  But at that moment, the tension and depravity of the scene felt all too real. LoL
