It was no secret that Ser Davos greatly disliked Melisdandre. He had felt this way about her for a very long time; even Stannis knew. But in his eyes, she was running his Lord into the ground. Did he not understand her cause, her purpose? The Red Priestess did not come all the way from Essos to simply ruin some High Lord's life. She did it to save the realm.
But, Ser Davos couldn't see it nor did he want to believe it. The bite of his blade proved as much. The Onion Knight called her evil and treacherous as the sword impaled her abdomen. Blood ran from her mouth when she took hold of his hand, forcing his arm backward which made him slowly remove the blade from within her flesh.
Melisandre could see the panic in his eyes once the ruby on her neck emitted that bright crimson glow, along with her scarlet irises. The ancient language of Asshai rolled from the Priestess' bloody mouth and the fires behind her grew larger, flickering with every syllable. Once the sword completely exited her she could feel the wound close and her organs heal. Davos took a few steps back, dropping the blood-stained blade on the floor. His expression mimicked the same one from when he witnessed her give birth to the Shadow Assassin. It was that same look of disbelief, fear, and horror.
Once Melisandre was fully restored she stood up straight, ceasing her chanting. "I will not die, yet, Ser Davos." She wiped the blood from her lips with her sleeve. "There is work still to be done. My mission has not been fulfilled. Until then…I will not accept death."
