consummated their relationship, and Deanna told Will for the first time that they are "Imzadi." However, after their return from the jungle, Lwaxana's violent objections to their relationship and Deanna's seeming compliance led Riker to drunkenly fall into bed with another woman. Deanna discovered them together when she appeared at his living quarters, having planned to tell him she had decided to defy her mother's wishes. Deanna and Will decided not to pursue a relationship and Riker left the planet shortly thereafter, not to meet Deanna again until they were both assigned to the Enterprise-D. In the future timeline, Commodore Data, now in command of the Enterprise-F, tells Riker that scientists studying the Guardian of Forever have discovered that Deanna's death was a focal point in time, causing the creation of a parallel timeline; his intention is to comfort Riker with the idea that Deanna lives on in another universe. Struck with a new suspicion, Admiral Riker has an autopsy performed on Deanna's corpse and discovers that she had been murdered via a poison that did not exist at the time she died. Deducing that someone had gone back in time to murder her and deliberately alter the timeline, Admiral Riker travels to the Guardian of Forever and goes back to the time of the Sindareen peace conference on the Enterprise-D, a short while before Deanna's death. He gives Commander Riker the antidote to the poison, and Riker administers it to Deanna. Her death is thus prevented, but Admiral Riker does not immediately return to his timeline, indicating that the danger to her has not yet passed. Commodore Data has also pursued Admiral Riker through the Guardian, feeling it is his duty to preserve the timeline by any means. He disables Commander Data and impersonates him, taking Deanna away from the peace conference with the intention of killing her. Admiral Riker realizes Data may try this, so he locates Commander Data and with him confronts Commodore Data, and they fight. As the peace conference attendees look on, Deanna finally becomes familiar enough with the representatives from the Sindareen (a race difficult to read empathically without sufficient exposure) to determine that they are deceiving everyone, and have no real peaceful intentions; the peace conference is only an attempt to stall for time so that their race can become more powerful. One of the Sindareen delegates is actually from the future and
