  • The Legends alter again the timeline by triggering Davies' time machine which erases the existence of time travel and, as a consequence, the Time Bureau as well as Ava Sharpe and Gary Green becoming Legends.
    • In this timeline, Ava Sharpe was never recruited by Rip Hunter so she never met the Legends.
    • Gary Green also never joined the Bureau in order to study Earth's champions.
  • Later, the Legends change once again the course of events by preventing Gwyn Davies' from dying in the explosion of his time machine.
    • They eventually use the machine, along with Davies, in order to time travel to another point in time.


  • The Legends mentions that Gwyn Davies looks similar to many of their past comrades, including Ray Palmer, Mick Rory and Martin Stein.
    • This is obviously a reference to Davies being portrayed by Matt Ryan who has previously portrayed one of the Legends, John Constantine.
