Kaecilius: How long have you been at Kamar-Taj, Mister...
Dr. Stephen Strange: Doctor!
Kaecilius: Mr. Doctor?
Dr. Stephen Strange: It's, Strange.
Kaecilius: Maybe. Who am I to judge?

[Repeated Line]
Dr. Stephen Strange: Dormammu, I've come to bargain!

* * *

Dr. Stephen Strange: Dormammu, I've come to bargain!
Dormammu: You've come to die. Your world is now my world. Like all worlds.
[He disintegrates Strange easily]
Dr. Stephen Strange: Dormammu, I've come to bargain!
Dormammu: You've come to die. Your world is now my... What is this? Illusion?
Dr. Stephen Strange: No, this is real.
Dormammu: Good.
[He kills Strange again]
Dr. Stephen Strange: [bored] Dormammu, I've come to bargain.
Dormammu: What is happening?
Dr. Stephen Strange: Since you gave Kaecilius power from your dimension, I brought some power from mine. This is time. Endless, looped time!
Dormammu: You dare?
[He kills Strange again]
Dr. Stephen Strange: Dormammu, I've come to bargain!
Dormammu: You cannot do this for ever.
Dr. Stephen Strange: Actually, I can. This is how things are now! You and me. Trapped in this moment. Endlessly.
Dormammu: Then you will spend eternity dying!
Dr. Stephen Strange: Yes, but everyone on Earth will live.
Dormammu: But you will suffer!
Dr. Stephen Strange: Pain's an old friend.
[Dormammu kills Strange again. And again. And again... ]
Dormammu: End this! You will never win.
Dr. Stephen Strange: No. But I can lose. Again. And again. And again. Forever. That makes you my prisoner.
Dormammu: No! Stop! Make this stop! Set me free!
Dr. Stephen Strange: No! I've come to bargain!
Dormammu: What do you want?!
Dr. Steven Strange: Take your zealots from the Earth. End your assault on my world. Never come back. Do it and I'll break the loop.

Dr. Stephen Strange: [After Mordo hands him a card] Well, what's this? My mantra?
Baron Mordo: The Wi-Fi password. We're not savages.

* * *

Thor: So Earth has wizards now, huh?
Dr. Stephen Strange: Tea?
Thor: I don't drink tea.
Dr. Stephen Strange: What do you drink?
Thor: Not tea.
[Strange uses his powers to transform the teacup Thor is holding into a stein of beer]
Dr. Stephen Strange: So, I keep a watch list of individuals and beings from other realms that may be a threat to this world. Your adopted brother, Loki, is one of those beings.
Thor: Worthy inclusion.
Dr. Stephen Strange: Yeah. So... why bring him here to New York?
Thor: It's a bit of a long story. Family drama, that kind of thing. But, we're looking for my father.
Dr. Stephen Strange: Oh, okay. So if you found Odin, you'd all return to Asgard promptly?
Thor: Oh, yes. Promptly.
Dr. Stephen Strange: Great. Allow me to help you.

Christine Palmer: Where have you been?
Dr. Stephen Strange: Well, after Western medicine failed me, I headed east, and I ended up in Kathmandu.
Christine Palmer: Kathmandu?
Dr. Stephen Strange: Yeah.
Christine Palmer: What? Like the Bob Seger Song?
Dr. Stephen Strange: 1975, Beautiful Loser, side A. Yeah. And I went to a place called Kamar-Taj and I... talked to someone called "The Ancient One." And I...
Christine Palmer: Oh. So you joined a cult.
Dr. Stephen Strange: No, I didn't. No, not exactly. No. I mean... They did teach me to tap into powers that I never even knew existed.
Christine Palmer: Yeah. That sounds like a cult.
Dr. Stephen Strange: It's not a cult.
Christine Palmer: Well, that's what a cultist would say.

* * *

The Ancient One: [On magic]  You cannot beat a river into submission; you have to surrender to its current, and use its power as your own.
Dr. Stephen Strange: I control it by surrendering control? That doesn't make any sense.
The Ancient One: Not everything does. Not everything has to. Your intellect has taken you far in life, but it will take you no further. Surrender, Stephen.

[Strange is experimenting with time manipulation using the Eye of Agamotto]
Baron Mordo: [bursting in] Stop! Tampering with continuum probabilities is forbidden!
Dr. Stephen Strange: I-I-I was just doing exactly what it said in the book!
Wong: And what did the book say about the dangers of performing that ritual?
Dr. Stephen Strange: I don't know, I hadn't gotten to that part yet.
Baron Mordo: Temporal manipulations can create branches in time. Unstable dimensional openings. Spatial paradoxes! Time loops! You wanna get stuck reliving the same moment over and over forever or never having existed at all?
Dr. Stephen Strange: They really should put the warnings before this spell.

* * *

The Ancient One: [As Doctor Strange is being moved through various dimensions of the Multiverse] You think you know how the world works? You think that this material universe is all there is? What is real? What mysteries lie beyond the reach of your senses? At the root of existence, mind and matter meet. Thoughts shape reality. This universe is only one of an infinite number. Worlds without end. Some benevolent and life giving. Others filled with malice and hunger. Dark places where powers older than time lie ravenous... and waiting. Who are you in this vast multiverse, Mr. Strange?

* * *

Dr. Stephen Strange: What did you just do to me?
The Ancient One: I pushed your astral form out of your physical form.
Dr. Stephen Strange: What's in that tea? Psilocybin? LSD?
The Ancient One: It's just tea... with a little honey.
Dr. Stephen Strange: What just happened?
The Ancient One: For a moment, you entered the astral dimension.
Dr. Stephen Strange: The what?
The Ancient One: A place where the soul exists apart from the body.
Dr. Stephen Strange: Why are you doing this to me?
The Ancient One: To show you just how much you don't know. Open your eye.
[She touches Strange's forehead and blasts him into an odyssey across dimensions]

* * *

Dr. Stephen Strange: [Sitting on the doorstep of Kamar-Taj, on the verge of tears] Don't shut me out. I haven't got anywhere else to go...
[The door suddenly opens, causing him to fall backwards into the building]
Dr. Stephen Strange: Thank you.

* * *

[The Cloak of Levitation clings to Strange and wipes away his tears]
Dr. Stephen Strange: Stop!

The Ancient One: I've spent so many year peering through time, looking at this exact moment. But I can't see past it. I've prevented countless terrible futures and after each one there's always another, and they all lead here but never further.
Dr. Stephen Strange: You think this is where you die?
The Ancient One: You wonder what I see in your future?
Dr. Stephen Strange: No. Yes.
The Ancient One: I never saw your future, only its possibilities. You have such a capacity for goodness. You've always excelled, but not because you crave success but because of your fear of failure.
Dr. Stephen Strange: It's what made me a great doctor.
The Ancient One: It's precisely what's kept you from greatness. Arrogance and fear still keep you from learning the simplest and most significant lesson of all.
Dr. Stephen Strange: Which is?
The Ancient One: It's not about you! When you first came to me, you asked me how I was able to heal Jonathan Pangborn. I didn't. He channels dimensional energy directly into his own body.
Dr. Stephen Strange: He uses magic to walk.
The Ancient One: Constantly. He had a choice, to return to his own life or to serve something greater than himself.
Dr. Stephen Strange: So I could have my hands back again. My old life?
The Ancient One: You could and the world would be all the lesser for it. I hated drawing power from the dark dimension but as you well know, sometimes one must break the rules in order to serve the greater good.
Dr. Stephen Strange: Mordo won't see it that way.
The Ancient One: Mordo's soul is rigid and unmovable, forged by the fires of his youth. He needs your flexibility, just as you need his strength. Only together do you stand a chance of stopping Dormammu.
Dr. Stephen Strange: I'm not ready.
The Ancient One: No one ever is. We don't get to choose our time. Death is what gives life meaning. To know your days are numbered, your time is short. You'd think after all this time I'd be ready, but look at me. Stretching one moment out into a thousand just so I can watch the snow.

Wong: What do you want, Strange?
Dr. Stephen Strange: Books on Astral Projection.
Wong: You're not ready for that.
Dr. Stephen Strange: Try me, Beyoncé.
[Wong remains silent]
Dr. Stephen Strange: Come on! You've heard of her, she's a huge star, right?
[Pause]
Dr. Stephen Strange: Do you ever laugh? Come on, just give me the book.
Wong: No.

Christine Palmer: Hey. It's OK. It's gonna be OK.
Dr. Stephen Strange: [Looking at his injured hands] Wha... What did they do?
Christine Palmer: Christine Palmer: They... rushed you in a chopper. But it took a little while to find you. The golden hours for nerve damage went by while you were in the car.
Dr. Stephen Strange: What... did they do?
Christine Palmer: Eleven stainless steel pins in the bones. Multiple torn ligaments... severe nerve damage in both hands. You were on the table for eleven hours.
Dr. Stephen Strange: [sobs] Look at these fixators.
Christine Palmer: No one could have done better.

Dr. Stephen Strange: I could have done better.

* * *

Christine Palmer: Stephen, you always spent money as fast as you can make it, but now you're spending money you don't even have. Maybe it's time to consider stopping.
Dr. Stephen Strange: No, now is exactly not the time to stop, because, you see, I'M NOT GETTING ANY BETTER!
Christine Palmer: But this isn't medicine anymore, this is mania. Somethings just can't be fixed.
Dr. Stephen Strange: A life without my work...
Christine Palmer: Is still a life. This isn't the end, there are other things that can give your life meaning.
Dr. Stephen Strange: [Bitter] Like what? Like you?
Christine Palmer: ...and this is the part where you apologise.
Dr. Stephen Strange: This is the part where you leave.

[Lucian's astral form approaches while Christine operates on Doctor Strange]
Dr. Stephen Strange: I'm gonna have to vanish now.
Christine Palmer: What?
Dr. Stephen Strange: Keep me alive, will you?

(If there are any more you would want to see, tell me and I'll get it down. :D)
