The conflict between Oliver and Prometheus will rage on for five more episodes until Arrow's season 5 finale on May 24. To finally stop the dangerous psychopath, Oliver will turn to an unexpected ally for help.
Arrow executive producer Wendy Mericle hints that whoever Oliver turns to will be very surprising and they'll have interestingl ties to his family. The most recent episode of Arrow saw Oliver disband Team Arrow and call in the Bratva but that doesn't seem like the surprising ally Mericle is describing.
“The alliances are going to be very surprising. You’re not going to believe who Oliver is working with to defeat Prometheus. It’s going to be really emotional. It’s going to be all about Oliver’s family, but not the family we’re thinking of right now. It’s going to end in a giant explosion, but not where we think it’s going to end, and the emotional punch is going to be bigger than the actual physical part of the bombs going off.”
Who do you think Oliver will turn to for help in stopping Prometheus? Deathstroke? Malcolm Merlyn (again)? The League of Assassins? A.R.G.U.S.? Perhaps Oliver will take a page out of Flash and the Legends' playbook and travel back in time to stop 'The Vigilante' from killing Prometheus' father?With five episodes until the season finale, Arrow returns from midseason hiatus on April 26 with "Dangerous Liasons", directed by Joel Novoa and written by Speed Weed & Elizabeth Kim.
