We're not Gods, Nora. We've just been given extraordinary abilities.

Barry

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

Cisco

We're gonna beat you.

Iris

Iris: This is my future!
Barry: No, no it's not! It's just a memory! One warped from the perspective of a sad, angry little girl! Don’t you get it? That person that we saw in there? The bad mom that Nora told us about? She doesn't even exist! In any timeline. I told you that you had to be different in the future but I was wrong. You don’t have to change who you are, you don’t even have to change the name of your newspaper! I know any future with you in itis going to be a good one. You just have to believe it too.

Nobody breaks up my family, you son of a bitch!

Iris

You’re an amazing woman Nora west Allen. I will always love you, past present and future.

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.

Barry: I never knew I was capable of caring for someone as much as I care for Nora.
Iris: I did. I’ve never met anyone with a bigger heart than you, Barry. So it’s no surprise to me that you're a fantastic father, just like you're a fantastic husband.

Captain Sing: When Joe gets back, the two of you will be a force to be reckoned with.
Cecile: Oh, we already are.

Cicada: You can’t win this fight.
Killer Frost: Yeah but I bet I can. They call me killer Frost. Now let me show you why.

I want a wife to grow old with. And a kid. And I don't want them to wonder all the time if their dad is in trouble.

Cisco

Iris: Being a parent is hard sometimes.
Barry: Yea, but there's nothing like it.

The Flash Quotes

One mystery I cannot figure out is why some people come into our lives and why some people go. Others become a part of you. Some friendships feel like they'll last forever and others end far too soon. Not every friendship is meant to last forever. What does last forever is the pain when that person is gone.

Barry: How long do you think he'll stay asleep?
Captain Cold: I like Shark Week. I'm not a marine biologist.
