Barry and Ralph in “Unfinished Business”

Barry

I know what killing DeVoe would do to you. You would be throwing away everything you've done to become a better man. To become a hero. You gotta realize that.

Ralph

You... are a moron.

Ralph

[voice shaking] I'm not afraid of DeVoe or what he might do to me. I am afraid of what he might do to you, and Iris, and Caitlin, and Cisco. Joe, Harry, Cecile. DeVoe has taken out everyone who has gotten in his way. And Team Flash, it will always be in his way.

Barry

[realizing] This was never about protecting yourself.

Ralph

I know that killing DeVoe would mean throwing away everything I've done to become a hero. But aside from my mom, this team is the only family that I have ever had, and I would throw myself into a furnace to keep them safe. DeVoe can not have them. They are mine!

Barry

What about what we want? You may not care about losing who you've become, but we do. We like Hero Ralph. Please don't take him away from us.
