Sue

Sue, unlike Jack Davenport and several young ladies introduced that way, is genuinely Henry Davenport's niece, although her married or maiden names never come up. She is a bright, attractive, warm-hearted woman with acute aerophobia when she first appears in "But Is It Art?". George is immediately drawn to her, almost despite the link to Henry, but is convinced he could be of zero interest to any woman, let alone a positive, bright and engaging one. Helen is practically forced to throw him at Sue, and it is she who tells him that he must go to Australia with Sue when the latter invites him. Sue is planning a whole new life for the two of them which seems filled with possibilities, but when Margaret Dent suffers a stroke, George makes the almost inexplicable decision to stay in England and look after her, although legally they are divorced and Margaret has brought him nothing but pain, including Deborah. Sue is presumably on board the plane which whooshes over George and Margaret's heads while they are in the zoo in "The Final Chapter".
