11. 'Fire and Blood' (Season 1, Episode 10)
Emotionally, the Season One finale was all about fallout, with characters and audience alike – particularly the freshly slain Ned Stark's children Robb, Sansa and Arya – still reeling from the shocking end of the previous episode. Visually, though, the final sequence was the crowning achievement: Daenerys Targaryen walked into the fire of her husband's funeral pyre and emerged, naked and unscathed, as the Mother of Dragons. Equal parts surreal, sexy, sinister and symbolic of her strength, it's the still the series' single most indelible image.
