[Spoilers MAIN] What does this line mean for Jon and Melisandre?
This speech from Beric Dondarrion has always interested me.
>Can I dwell on what I scarce remember? I held a castle on the Marches once, and there was a woman I was pledged to marry, but I could not find that castle today, nor tell you the color of that woman's hair. Who knighted me, old friend? What were my favorite foods? It all fades. Sometimes I think I was born on the bloody grass in that grove of ash, with the taste of fire in my mouth and a hole in my chest. Are you my mother, Thoros?
It shows how resurrection slowly erodes the continuity of self and that how the resurrector becomes something like an anchor point for identity or a symbolic mother.
In other words, "The person I used to be is gone, and the one who brings me back now anchors what I am."
How could this apply to Jon? He will likely be resurrected by Melisandre or at least she will have some involvement.
Jon's resurrection will be different from Beric. Not only did Jon die only once, but he has something Beric doesn’t: his warging link with Ghost. That means part of him likely continues during death instead of being fully severed. So he will come back more intact than Beric or Stoneheart.
But he will still change. He will be deeply traumatized. He will be even more unsure of who he truly is.
And I believe that Melisandre, good or bad, will be that anchor that'll steer him, especially when you consider the absence of a maternal figure in Jon's life.
