One of the most visited scenes in A song of ice and fire is Sandor waiting for Sansa in her room during the battle of the blackwater, asking for her to sing for him, with the million and one meanings people derive from that chapter regarding Sandor helping Sansa wake up from the fairytale/nightmare she’s been living in - Loss of innocence. Did she kiss him? Probably not. Unreliable narrators, remember?
