The male protagonist's time flow is from 1988 to 2024, and the female protagonist's granddaughter flows from 2024 to 1988. In 1988, the male protagonist pushed the female protagonist, and the female protagonist died. In 1997, the female protagonist killed her black partner. In 1988, the granddaughter told the male protagonist that she was sorry. In 1997, the granddaughter stole the key to the plane and lost it in 1988.
Isotope killing this, from the research of Dr. India, it can be seen from the research of Dr. India that it does not die immediately after injection, but needs to be switched on and off, and then controlled to die, as can be seen from the three experimental pigs. The Doctor Control Device in 2042 killed the rioters with the registered isotopes from 2042 to 1988 one at a time, until the First Subject was killed.
Since the past is gone, the situation in 2042 will not appear in the future. The male protagonist in 1988 will also go to work as usual, and the female protagonist will not appear. This ending is similar to the ending of the film's time and space clues. Too lazy to think about parallel universes.
