Creep is amazing with the things I come up with, so he'll love this:
I was re-watching episode 2 of season 2, after sending perkana some links.
Davos (Stannis' knight) goes into Stannis' war chamber with his son, Mathos. They talk about the naval strategy involved in attacking King's Landing, until the fire priestess gives Stannis a look. Stannis says "leave us," and the men go to leave. As they are heading out, the witch stops Mathos - the one who completely believes in her religion - and whispers in his ear. When the men are gone, Stannis asks the witch what she said to Mathos. She answers, "I told him that death by fire is the purest death." Stannis asks why she said that, and she answers, "because it is true."
Stannis ends up fucking her on the war table, but that's beside the point. In episode 9, Mathos dies in Blackwater Bay, while approaching King's Landing - engulfed by wildfire.
