Spock/Starfleet/Christopher Pike/Searching for the Red Angel

Following the end of the in 2257, Spock took an unspecified leave of absence from Starfleet. He had accumulated a number of months during the five-year mission which, according to Pike, took a toll on the whole crew as well as Spock. Upon reviewing Spock's personal log entries on the Enterprise, Michael Burnham learned that Spock had been having visions ever since he was a boy, and that he had had premonitions of the mysterious red bursts that the was likewise investigating, which Spock believed were related to his childhood visions of "the Red Angel." ()
Spock followed his visions to an unknown planet where he encountered the Red Angel. Through a mind meld, he discovered that it was a Human but one clad in a suit far beyond 23rd century technology. Through the meld, he received a vision of the destruction of Earth, , Andor, and Tellar, and began experiencing time non-linearly. () He decided to have himself committed to the psychiatric unit on Starbase 5. In doing so, he requested that Starfleet not inform his family about the matter, including his father and foster sister. While there, he was observed to display acutely emotional dissociation and extreme empathy deficits. When he was told the red bursts had occurred as he had predicted, Spock broke out of the facility, disabling three of his doctors with Vulcan nerve pinches and fleeing on a shuttlecraft. ()
Starfleet subsequently claimed that Spock had murdered his doctors and made finding him a priority. The and Section 31 became involved in the search. Aware he was being pursued, Spock abandoned his shuttlecraft in the Mutara sector and secretly returned to Vulcan. There, his mother hid him in a sacred crypt where katra stones shielded him from telepathic searches. Spock had become delusional and incoherent, unable to bear the experience of viewing time non-linearly, and repeated the First Doctrines of Logic and a sequence of numbers over and over. Burnham convinced Amanda to take her to Spock, but Sarek followed Burnham and convinced her that the best way to help Spock was to hand him over to Section 31. Burnham took Spock to the Section 31 ship NCIA-93 where Captain Leland promised he would help repair Spock's mind. However, warned Burnham that Leland intended to extract Spock's memories using a process that would destroy his mind. At Georgiou's suggestion, Burnham overpowered her and took Spock from the Section 31 ship in a shuttlecraft. ()
Burnham realized that, since Spock's mind had regressed to childhood, the sequence of numbers he had been repeating was reversed due to his L'tak Terai. In the opposite order, the numbers represented the coordinates for Talos IV. Burnham thus set a course for that planet. There, the Talosians and Vina agreed to help heal Spock and subsequently projected illusions to the pursuing NCIA-93 to allow Burnham and Spock to escape to the which was commanded by his old friend Captain Christopher Pike while the was down for repairs.
