Weddings were ceremonies in which two people were married.
The Doctor Edit
Over the course of his life the Doctor was married more than once.
In 1562, the wedding between the Tenth Doctor and Queen Elizabeth I was attended by the Eleventh Doctor, Clara Oswald and the War Doctor. This came about after the Tenth Doctor accidentally proposed to her in a ploy to prove that the Queen was in fact a Zygon. When it turned out that it was instead his horse that was the Zygon, though, he was forced to carry through with the marriage. (TV: The Day of the Doctor)
In Hollywood in 1952, the Eleventh Doctor accidentally found himself engaged to Marilyn Monroe, and ended up having to leave the party with her to get married. Marilyn got his phone number and attempted to call him, but he denied the legitimacy of the chapel where they were apparently married. (TV: A Christmas Carol)
Weddings of the Doctor's companions Edit
In 1986, the Ninth Doctor and Rose Tyler attended the wedding of Pete Tyler and Jackie Prentice. A year later, Pete and Jackie attended the wedding of Stuart Hoskins and Sarah Clark, during which Pete was hit by a car outside the church and killed. (TV: Father's Day)
The Seventh Doctor originally did not attend the wedding of Alistair Gordon Lethbridge-Stewart and Doris, but later changed time to a minor extent so that he did attend it. (PROSE: A Romantic Evening)
On 29 October 2009, the wedding of Sarah Jane Smith and Peter Dalton was revealed to be part of the Trickster's scheme and averted with help from the Tenth Doctor. (TV: The Wedding of Sarah Jane Smith)
Donna Noble Edit
Donna later married Lee McAvoy while in CAL's virtual world. The two lived a virtual life until the Tenth Doctor and River Song freed them from the virtual world. Donna was unable to find Lee again afterwards even though he was real and not a construct of the virtual world. (TV: Forest of the Dead)
After Donna stopped travelling with the Doctor, she got married again in spring of 2010, this time to Shaun Temple. The Tenth Doctor secretly attended this wedding. The first and last time the Doctor saw Donna, she was in a wedding dress. As a final gift to Donna, the Doctor gave her a lottery ticket to ensure her and her new husband's financial future bought with money borrowed from her deceased father. (TV: The End of Time)
