chunk: Mortally wounded, Khan activates Genesis, which will reorganize all matter in the nebula, including the Enterprise. Though Kirk's crew detects the activation of Genesis and attempts to move out of range, they will not be able to escape the nebula in time due to the ship's damaged warp drive. Spock goes to the engine room to restore the warp drive. When McCoy tries to prevent Spock's entry, as exposure to the high levels of radiation would be fatal, Spock incapacitates the doctor with a Vulcan nerve pinch and performs a mind meld, telling him to "remember". Spock successfully restores power to the warp drive and the Enterprise escapes the explosion, though at the cost of his life. The explosion of Genesis causes the gas in the nebula to reform into a new planet, capable of sustaining life.
