Barry and Henry in “Unfinished Business”

Barry

I can save mom.

Henry

At what cost? You said time won't change. What if it changes you?

Barry

I don't care.

Henry

I do. I am in awe of the remarkable person that you are becoming. All the things you achieved and not just as the Flash, but you, Barry. Your honesty, your heart. You're always a hero, and your mom would be just as proud. And if she had a say in this, if she thought for one second that you going back to save her would mean losing what makes you so special, she would never want that! [Barry sobs] Barry, what I hope for you, maybe the greatest thing that a father can hope for his son is that one day you will have a son yourself and then you will know how much I truly love you.
