Season one, episode ten — called "Nobody is Ever Missing" — sees Shiv Roy (Sarah Snook) marry Tom Wambsgans (Matthew Macfayden) in an elaborate ceremony at Eastnor Castle in Scotland. Things aren't looking good from the start, as in episode nine, Tom confronts Shiv about having an affair with a former coworker, and Shiv uses that as a chance to try to manipulate Tom into sharing details about the cruise ship disasters he helped cover up.
By episode ten, things have reached a boiling point. Kendall (Jeremy Strong), who has been plotting a takeover of Waystar RoyCo for almost the entire season, tells Logan about his plan to buy out the company during the reception, infuriating Shiv. Meanwhile, a satellite that Roman (Kieran Culkin) prepared to launch explodes, though no one was killed, and Connor decides he wants to run for president of the United States.
After night falls, Shiv and Tom have a far-from-ideal wedding night, as she tells him about her affair and then says she wants to have an open relationship. But things turn out immeasurably worse for Kendall, who asks a caterer (Tom Morley) to help him acquire drugs during the reception. While driving to pick them up, Kendall accidentally drives off a bridge and the car sinks into a lake. Kendall makes it out, but the caterer drowns — and of course, Logan finds out and uses the event to blackmail Kendall into giving up his attempt to take over Waystar RoyCo.
