During a stakeout of murderer Irwin Lukesh, Doggett sees Reyes attacked by Lukesh but then we see Reyes and Doggett in her apartment, apparently both fine. Elsewhere at the same time, Doggett is shot and Lukesh indentifies Reyes as the shooter. While Reyes is asked for her badge and gun by AD Follmer and Doggett lies in hospital near death, the conflicting circumstanses of the stakeout and Doggett's shooting do not add up and it becomes clear that Lukesh posesses the power to switch between parallel universes and alter the events in each.
