The Flash Season 5 Quotes

Nora sometimes we fail because all we can worry about is not failing.

Cisco

Ralph: I just thought if we were getting a night off from stopping Cicada we could just go out and have some fun you know?
Cisco: And I want that too, but after we figure out this cure.
Ralph: You know my mom's friend Doug, he had a saying: If you’re always waiting to live your life you're gonna die before it starts. And Doug? He would know, he operated a Zamboni. May he rest in peace.
