The 2379 wedding of William Riker and Deanna Troi, celebrated on Earth with the Enterprise-E crew before Riker left to command the USS Titan.
The wedding reception opens Star Trek Nemesis. Riker and Troi, whose romance began on Betazed years before Encounter at Farpoint and resumed during Star Trek: Insurrection, marry on Earth in Alaska, Riker's home.
Picard, as best man, gives a toast lamenting the loss of his first officer and counsellor. Data sings Blue Skies for the couple, Guinan and Beverly Crusher are among the guests, Wesley Crusher is seen in a Starfleet uniform, and Worf suffers from the after-effects of Romulan ale.
A second ceremony is planned on Betazed, where custom has everyone attend unclothed, to Worf's dismay. The journey there is broken by the discovery of B-4 and the mission to Romulus. Afterwards Riker takes command of the Titan with Troi aboard.
