Did You Know?


The first full Arrowverse crossover to include the Supergirl episode in the actual plot of the crossover; the previous year's Invasion! storyline only included a brief teaser scene at the end (which was repeated in the episode of The Flash that followed) and a few brief teaser shots of Team Flash's attempt to reach Kara throughout on the Supergirl side of things, while the year before that the show was on a separate network and unable to cross over at all. Supergirl and some of the other characters have been included in individual crossover episodes, but those events took place entirely on one show ("World's Finest" on Supergirl (episode 1x18) and "Duet" on The Flash (episode 3x17)) with maybe a teaser on the other for continuity.

Felicity Smoak: Did I have some of Cisco's 10,000 proof cocktail that he gives to Barry so that he can get drunk, or are you asking me to marry you?
Oliver Queen: What if I was?
Felicity Smoak: Would...
Oliver Queen: That was silly. I am... I am....
