He also sincerely congratulates them both, and says that Mary deserves as good a man as John. He says this shows what an arsehole he is, and how good a man John Watson is to consider Sherlock his best friend. Sherlock then goes about insulting most of the guests and ridiculing the institution of marriage. He claims to have gone through a range of emotions before expressing his gratitude, then admits that he'd not said anything out loud. Sherlock rattles through the rest of the telegrams and then recounts the story of John asking him to be best man. One is from Mike Stamford, another from Cam, who wished Mary's family was around to see the wedding. Sherlock remembers the telegrams, and begins to read them out. Sherlock begins his speech, and is lost for words, and we flash back to John preparing to ask Sherlock for the honour of being best man. The reception begins and John thanks Sholto for coming. Sherlock interrogates all of Mary's male friends to see the likelihood of infidelity, causing one of them to very carefully keep his distance from Mary after Sherlock had warned him to do so. After the ceremony, John and Mary leave the church, and a photographer takes their picture. We see a man getting ready for the occasion: James Sholto, John's old army commander.

Mrs Hudson then speaks to Sherlock about the big day coming up: John's wedding to Mary. Lestrade abandons the arrest and sends police units Sherlock's house, only to find that the help needed was with writing a best man's speech. As he is moving in, Sherlock texts him urgently for help at Baker Street. He gets increasingly frustrated with each new incident, but finally the police force manage to corner the gang.
