Like Chronitons Through the Hourglass

A bandaged Pike wakes up in sickbay. M'Benga says that two weeks ago, a shuttlecraft accident left Pike with amnesia and Spock in a coma so that he requires a "live heart transplant". Pike visits the ship's counselor but is interrupted by Uhura, who has just learned that she is Pike's daughter. The strange events and odd melodramatic speech of his colleagues lead Pike to suspect that supernatural entities may be involved, and he soon learns that Trelane has imprisoned the crew in a soap opera, for his academic project to study human emotion. Meanwhile, La'An has captured Spock's half-brother Sybok to use as a heart donor. Sybok escapes her, but decides to donate anyway after an emotional speech from La'An. While attempting to resolve his family drama with Uhura, Pike instead meets Juliet, Pike's daughter from the full happy life he experienced with Marie.
