Set in 1981, the episode depicts the engagement of Charles, Prince of Wales (O'Connor) to Lady Diana Spencer (Corrin), culminating in their wedding.

She is comforted by the wealth of supportive letters she receives from the public but is unable to arrange a meeting with Queen Elizabeth and develops bulimia.

Morgan chose not to depict the wedding of Charles and Diana itself, focusing instead on the couple's engagement period; according to Corrin and O'Connor, this was because the ceremony can easily be viewed on YouTube.

[5] The scene was initially edited to be scored by Martin Phipps's soundtrack music before John's estate agreed to the use of "Song for Guy", resulting in a stylistic departure for The Crown.

In a five-star review, Vulture.com's Sarene Leeds identified the episode's unflinching depiction of the monarchy's shortcomings and the "abysmal chasm" between Diana and Charles.

Club, Caroline Siede praised the episode's foregrounding of Diana's youth to imply a "medieval" aspect to her marriage to the older Charles.

Siede also noted Corrin's skill in "conveying the physicality of a 19-year-old", although she felt that the episode could have held Charles accountable for her unhappiness to a greater degree.

Asserting that Corrin's depiction is "hands down the best onscreen Diana we’ve ever seen", O'Keefe praised her "technical craft" and allusions to her "hidden despair".
