Supergirl sisters Kara and Alex Danvers and Legends of Tomorrow’s Sara Lance are among several hundred guests attending the wedding of Barry Allen and Iris West in this year’s DC Crossover Event.
Alex (Chyler Leigh) joins Kara (Melissa Benoist) at the steps leading up to the church, where she chats with Sara Lance (Caity Lotz).
Giggling sisters 
Danvers sisters walk unsteadily up the steps into the church, arms around one another.
And reset.
