'Downton Abbey': Anna and Mr. Bates (Season 2, Episodes 1 and 8)
Most of the relationships on Downton Abbey could be described as long-simmering, since it usually takes several years before the show's upstairs-downstairs couples have their first kiss. But it was especially fun watching the romance play out between kindhearted housemaid Anna and her perpetually unlucky paramour, the crippled valet Bates. After circling each other the first season, these two finally smooched in the second-season premiere – pretty scandalous by Downton standards, as it only took them four years to swap spit, whereas Lady Sybil and her controversial beau, chauffeur Tom Branson, took six. But it was their hastened wedding in Episode Eight that cemented the depth of their love, as Anna pushed Bates to marry her so she could be his next of kin when he was inevitably arrested for the murder of his insidious wife, Vera.
