The Doctor

Ryan: Hey! You shot him!
Graham: Yeah, but just the foot. Just in the foot. Just to shut him up. Don't tell The Doc. She'll be livid.

Tim Shaw: You are no warrior.
Graham: No. I'm the better man.

Oliver [As The Flash]: YOU HAVE FAILED THIS CITY.
Cisco: Pretty sure that's not your line.

Barry: Tell her she's your lightning rod.
Oliver: I'm not saying that.
Barry: Just say it, trust me. It works every time!

Andinio: I don't have to answer all these questions.
The Doctor: That's what my teachers used to say. Usually, just as they quit teaching.

Iris: You, Barry Allen, have always been and will always be, the man that I love.
Barry: No matter what mask I wear I will always show you my true face.
Iris: I need you to promise me something, Barry. Promise me that when we figure out who did this to you and when you get your speed back and you're finally back in my arms, that you'll come back to me.
Barry: Of course I'll come back.
Iris: Barry I heard what you said right before you took that shot. You're the Green Arrow now. But please don't become Oliver Queen.

Barry: If you touch her-
Oliver: I didn't touch her!
Barry: You thought about it!

Ryan: You think that's what Nan would want?
Graham: No, I think your Nan would want to be alive. She actually liked being alive and she was really good at it. And she'd say to me,'Graham, if you get the chance, you send that little piece of rubbish to kingdom come,' Because, you know why? Your Nan might've been kind, but she was also tougher than you and me put together.

Whatever happened to doors? Don't aliens bother with doors?

Ryan

The Doctor: Grenades. As insurance policy.
Paltraki: You think that's smart?
The Doctor: I think it's a precaution. I like precautions. Always take precautions. Especially when you don't know what you're doing.

Ryan: What happened to 'never do weapons'?
The Doctor: It's a flexible creed. Door, locks, walls, buildings. Fair game. If it can be rebuilt, I'll allow it.
