Recced because: Epic and brilliant, this story spins out a non-linear adventure and love story for Ian and Barbara, and unexpectedly but beautifully, tells us about Sarah Jane, as well. There's UST, romance, a touch of sex, happiness, ever-afters, danger, and adventure galore – everything that happens in life, especially a life with the Doctor, all of it, the good and the bad. The guest stars are all perfectly used, and with some terrific lines: "It's enough to give anyone a headache," Harry said sympathetically. / "Oh, Ian's just easily baffled," said Barbara which made me laugh out loud, and "It's a lovely elbow," said Barbara politely. / "Thank you," Ian said. "But I have heard good things about certain other portions of my anatomy." which was too perfect – and sexy – for words, this is an absolute delight.
