We watch "The Husbands of River Song" (Series 9, Episode 13) where (spoilers!) this Doctor meets up with his clueless wife River Song whilst she adds to her polyamorous menagerie of spouses. Whilst said polyamory is occurring, the Doctor says "Hello Sweetie" to River who finally recognizes him whilst she plots the death of her latest husband, King Hydroflax. Afterwards, River and the Doctor meet up for their final date at the Singing Towers of Darillium. What with his new haircut and suit and tears and foreknowledge of their penultimate time together... I’m not crying! You’re crying!
