Supergirl and Barry in “Unfinished Business”

You really think this is gonna work?

Barry

Well, watching Livewire and Banshee work together reminded me of something that we tried on my Earth once. You and I join forces. Literally. We combine your speed with my speed, and if you throw me forward at your fastest, then I might just break the dimensional barrier and get back home.

[amused] What, you mean, like... a race?

Barry

Yeah, I guess.

Barry

[in good humor] Think you can keep up, Girl of Steel?

[with equal humor] Just you watch, Scarlet Speedster.
