Good stuff there at the end. Really seems that not only Melisandre is losing her faith but perhaps her power as well(maybe finally succombing to age), she looked quite weary as well. Or maybe she always did that when retiring for the night. I wonder if her "last act" in the world will be her doing.....:ninja .
I do like her losing faith as a bit of her character arch. How in the beginning she was so confident, so sure of herself and her mission but cannot successfully carry them out. Where you have Thoros(fellow Red Priest for those who may not remember), pretty much a non-practicing priest, performs an act that she didn't even think was possible(Beric's resurrections). Between that and her reading the fires wrong, she is lost and probably scared. I think she also mentioned before that she didn't need warmer clothes because the Red God kept her warm...yet here we have her crawling into bed and under blankets...metaphor anyone?
