We won’t see Russia or Lian Yu in the 20th episode of Arrow Season 5, but we will see some flashbacks, according to some intel posted at TV Line.
The episode which is said to finally address the Oliver and Felicity breakup will instead have flashbacks from a different part of Arrow history.
“The flashbacks are to a different time period, as we occasionally do,” Arrow EP Marc Guggenheim told the site. “They take place between Seasons 4 and 5.”
And there you have it. Guggenheim didn’t confirm that the flashbacks are Olicity, but considering Stephen Amell said all of his scenes in the episode, we’re assuming it is indeed Olicity. Look for this episode in early May.
