On March 28th at 8pm, the Flash breaches usually unbreachable dimensional demarcations, finding himself stranded in National City and on the CBS network. Wait. If he’s in National City, and on CBS between the hours of 8pm-9pm, that means…YES! It means he’ll be showing up on Supergirl! In the forthcoming Supergirl episode entitled, “World’s Finest,” Barry Allen shows up, charms the heck out of Supergirl, helps her take on the Silver Banshee/ Livewire cooperative and gets a little assistance in multiversal re-breaching. Yup. Oh, and of course, Flash and Supergirl race; they’re curious about their personal limits comparable to others similarly gifted. Would you like to see what that looks like? Good. Here’s what it looks like:

Here’s the official synopsis from CBS!
“World’s Finest” – Kara gains a new ally when the lightning-fast superhero The Flash (Grant Gustin) suddenly appears from an alternate universe and helps Kara battle Siobhan, aka Silver Banshee, and Livewire in exchange for her help in finding a way to return him home, on SUPERGIRL, Monday, March 28 (8:00-9:00 PM) on the CBS Television Network. Grant Gustin crosses over as The Flash.
So, who’s going to win? Circle A or B:
A. Supergirl, the girl who can fly like, Mach 2. Maybe.
B. Flash, the boy who can crisscross dimensions. Hmmmm.
