In case that wasn’t enough, it’ll also double as the third installment in the 4-part crossover event.
As those who have been keeping up to date with the crossover will already know, last night’s episode of The Flash ended with Oliver (Stephen Amell) and a number of the other Arrow cast members being abducted by The Dominators.
This is a big week for the Arrowverse.
Not only is it currently embarking on its most ambitious crossover event to date, bringing together characters of The Flash, Arrow, Legends of Tomorrow, and Supergirl in a battle to fight the terrifying alien race known as The Dominators, but tonight is also the 100th episode of Arrow.
