[Cut to Nebula suspended in the interrogation room seen earlier, while a guard puts her back together. Nebula ejects her eyepiece; disposing of the guard when he comes to replace it. She walks to a console, dragging her dislocated metal foot behind her, and inputs a code.]

Nebula: Mantis, listen very carefully. I need you to meet me on Titan.

[Cut to Peter Parker, Tony Stark, and Doctor Strange aboard the ship]

Peter Parker: (To Tony) Hey, what's going on?

Tony: I think we're here. I don't think this rig has a self-park function. (Instructing Peter to put his arm in the machine for piloting) Get your hand into this steering gimbal. Close those around it. You understand?

Peter Parker: Yep, got it.

Tony: This was meant for one big guy, so we gotta move at the same time.

Peter Parker: Okay. Okay. Ready.

Tony: We might wanna turn.

Peter Parker: Turn! Turn! Turn!

(Strange creates a shield around them with the help of Lucy to prevent them from being killed in the landing.)

(The ship, now partially gone, lands on Titan)

Tony: (To Strange) You alright?

Tony: That was close. I owe you one.

(Peter Parker descends from above in spider-like fashion)

Peter Parker: Let me just say, if aliens wind up implanting eggs in my chest or something...And I end up eating you, I'm sorry.

Tony: (While pointing at Peter) I don't wanna hear another single pop culture out of you for the rest of the trip. You understand?

Peter Parker: I'm trying to say that something is coming.

(A grenade rolls into view, and Peter, Strange, Lucy and Tony get back. Star-Lord, Drax, and Mantis appear in the doorway)

Drax: (Yelling) Thanos!

(The Cloak of Levitation flies at Drax's face and whips him around. Star-Lord pins Iron Man to the wall with a magnetic disc)

Peter Parker: (While crawling backward from Mantis) Whoa, whoa, whoa, whoa! Please don't put your eggs in me!

(Peter webs Mantis' arms to her body, and Star-Lord flies at him in from the side, kicking him down.)

Star-Lord: Stay down, clown.

(Tony fires at the flying Star-Lord as Peter Parker extends his spider legs and jumps at him, but Star-Lord throws an electric cord that wraps around Parker sending him to the ground)

Drax: (Struggling with the Cloak of Levitation) Die, blanket of death!

(Iron Man pulls free of the magnet. They pull weapons on each other. Star-Lord has Peter Parker in a head-lock, while Iron Man stands over Drax with a gun, and Doctor Strange stands ready near Mantis and lucy has her Shield spell)

Star-Lord: Everybody stay where you are. Chill the F out. (Quill powers off his helmet) I'm gonna ask you this one time. Where's Gamora?

Tony: Yeah, I'll do you one better. Who's Gamora?

Drax: I'll do you one better! Why is Gamora?

Star-Lord: Tell me where the girl is, or I swear to you, I'm gonna French fry this little freak.

Tony: Let's do it! You shoot my guy, I blast him. Let's go! (Tony extends his nanotech gun)

Drax: Do it, Quill! I can take it.

Mantis: No he can't take it!

Strange: She's right. You can't.

Star-Lord: Oh yeah? You don't wanna tell me where she is? That's fine. I'll kill all three of you and beat it out of Thanos myself. (To Parker) Starting with you.

Lucy: Wait, what, Thanos? [she looks to Strange]

Strange: All right, let me ask you this one time. What master do you serve?

Star-Lord: What master do I serve? What am I supposed to say? "Jesus"?

Tony: You're from Earth?

Star-Lord: I'm not from Earth. I'm from Missouri.

Tony: Yeah, that's on Earth dip-shit. What are you harassing us for?

Peter Parker: So, you're not with Thanos?

Star-Lord: With Thanos? (scoffs) No, I'm here to kill Thanos. He took my girl- Wait, who are you?

Peter Parker: We're the Avengers, man.

Star-Lord: Oh.

Mantis: You're the ones Thor told us about.

Tony: You know Thor?

Star-Lord: Yeah. Tall guy, not good-looking, needed saving.

Tony: Where is he now?

[Cut to Nidavellir where Eitri is showing Thor, Rocket, and Groot the mold for Stormbreaker]

Rocket: This is the plan? We're gonna hit him with a brick?

Eitri: It's a mold. A king's weapon. Meant to be the greatest in Asgard. In theory, it could even summon the Bifrost.

Thor: Did it have a name?

Eitri: Stormbreaker.

Rocket: That's a bit much.

Thor: So how do we make it?

Eitri: You'll have to restart the forge. Awaken the heart of a dying star.

Thor: Rabbit, fire up the pod.

[Cut to Titan where Quill is measuring the planet's tilt. Mantis is jumping in the low gravity]

Quill: The *heck* what happened to this planet? It's eight degrees off its axis. Gravitational pull is all over the place.

Tony: Yeah, we got one advantage. He's coming to us. We'll use it. All right, I have a plan. Or at least the beginnings of one. It's pretty simple. We draw him in, pin him down, get what we need. Definitely don't wanna dance with this guy. We just need the gauntlet.

(Drax yawns)

Tony: Are you yawning? In the middle of this, while I'm breaking it down? Huh? Did you hear what I said?

Drax: I stopped listening after you said, "We need a plan."

Tony: (To Quill) Okay, Mr. Clean is on his own page.

Quill: See, "not winging it" isn't really what they do.

Peter Parker: Uh, what exactly do they do?

Mantis: Kick names, take ass.

Drax: (Quietly as he shifts to a commanding position beside Mantis) Yeah, that's right

Tony: (Tony stands for a moment with an expression of hopelessness) Alright, just get over her, please. Mr. Lord, can you get your folks to circle up?

Quill: "Mr. Lord." Star-Lord is fine. (Motions to Drax and Mantis)

Tony: We gotta coalesce. 'Cause if all we come at him with is a plucky attitude.."

Quill: Dude, don't call us plucky. We don't know what it means. Alright, we're optimistic, yes. I like your plan. Except it sucks, so let me do the plans, and that way it might be really good.

Drax: Tell him about the dance-off to save the universe.

Tony: What dance-off?

Quill: It's nothing.

Peter Parker: Like in Footloose, the movie?

Quill: (Excitedly) Exactly like Footloose. Is it still the greatest movie in history?

Peter Parker: It never was.

(Quill frowns sadly at him)

Tony: Don't encourage this, alright?

Peter Parker: Okay.

Tony: We're getting no help from Flash Gordon here.

Quill: Flash Gordon? By the way, that's a compliment. Don't forget, I'm half human. (Quill points at Stark and Parker) So that 50% of me that's stupid... That's 100% you.

Tony: Your math is blowing my mind.

Mantis: Excuse me, but...Do your friends often do that?

(Strange and Lucy are sitting cross-legged, their hands poise in a mystic gesture with the Time Stone suspended between them. their eyes are closed, and their head is jerking rapidly from side to side)

Tony: Strange, Lucy, we alright?

(Strange and Lucy seems to snap out of it as they starts forward, letting out a cry)

Tony: You're back. You're alright. Hi.

Peter Parker: Hey, what was that?

Strange: (Speaking breathlessly) we went forward in time to view alternate futures. To see all the possible outcomes of the coming conflict.

Quill: How many did you see?

Strange: 14,000,606.

Tony: How many did we win?

(Lucy pauses a while before answering)

Lucy: Two.

[Cut to Vormir, where Thanos and Gamora have just appeared outside a mountain]

Thanos: The stone had better be up there...For your sister's sake.

(Cut to inside the mountain where Thanos and Gamora stand before a cloaked, faceless figure there to guard the way)

Stonekeeper: Welcome, Thanos, son of Eros. Gamora, daughter of Thanos.

Thanos: You know us?

Stonekeeper: It is my curse to know all who journey here.

Thanos: Where's the Soul Stone?

Stonekeeper: You should know...It extracts a terrible price.

Thanos: I am prepared.

Stonekeeper: We all think that at first. (The figure glides farther out of the shadows and reveals the face of who we know to be Red Skull from Captain America: The First Avenger) We are all wrong.

(Cut to the Red Skull leading Thanos and Gamora to an outside pinnacle)

Thanos: How is it you know this place so well?

Red Skull: A lifetime ago, I, too, sought the stones. I even held one in my hand. But it cast me out, banished me here. Guiding others to a treasure I cannot possess.

(They come to the edge of mountaintop, and stop at the precipice)

Red Skull: What you seek lies before you. As does what you fear.

Thanos: What's this?

Red Skull: The price. Soul holds a special place among the Infinity Stones. You might say it has a certain wisdom.

Thanos: Tell me what it needs.

Red Skull: To ensure that whoever possesses it... Understands its power... The stone demands a sacrifice.

Thanos: Of what?

Red Skull: In order to take the stone you must lose that which you love. A soul...For a soul.

(Gamora begins to laugh at the irony of the situation)

Gamora: All my life, I dreamed of a day...A moment when you would get what you deserved. And I was always so disappointed. But now...You kill and torture...And you call it mercy. The universe has judged you. You asked it for a prize, and it told you no. You failed. And do you wanna know why? Because you love nothing. No one.

Thanos: (Turning to face Gamora with tears in his eyes) No.

Gamora: Really? Tears?

Red Skull: They're not for him.

(Gamora looks at Red Skull, and seems to realize what is about to happen)

Gamora: No. This isn't love.

Thanos: I ignored my destiny once. I cannot do that again. Even for you. I'm sorry, little one.

(Thanos grabs Gamora by the arm and takes her to the precipice)

Gamora: No!

(She tries in vain to brake from his grasp but he soon throws her over the side, and watches sorrowfully as she falls to her death)

[Cut to Thanos lying in water. He opens his hand and sees that he now has the Soul Stone.]

[Cut to the Quinjet where Sam is piloting Rhodey, Steve, Natasha, Wanda, and Vision]

Sam: Drop to 2600, heading 0-3-0. I hope you're right about this, Cap. Or we're gonna land a lot faster than you want to.

(The Quinjet passes through a force field into Wakanda)

Okoye: (Walking with T'Challa and a band of the King's Guard) When you said we were going to open Wakanda to the rest of the world...This is not what I imagined.

T'Challa: And what did you imagine?

Okoye: The Olympics. Maybe even a Starbucks.

(The occupants of the Quinjet descend the ramp)

Bruce Banner: (To Lincoln and Rhodes) Should we bow?

Lincoln: Yeah, he's a king.

Steve Rodgers: Seems like I'm always thanking you for something. (Shaking hands with T'Challa)

(Bruce and Lily bow in front of him)

Rhodes: What are you doing?

T'Challa: Uh, we don't do that here. (He dissuades with a motion of his hand) So how big of an assault can we expect?

(The group begins to walk back the way it come to greet the guests)

Bruce Banner: Uh, sir, I think you can expect quite a big assault.

Steve Rodgers: How are we looking?

T'Challa: You will have my King's Guard, the Border Tribe, the Dora Milaje, and...

Bucky: (Walking forward toward Steve) A semi-stable, 100-year-old man.

(The two friends share a hug)

Steve: How have you been, Buck?

Bucky: Uh, not bad, for the end of the world.

(Cut to inside Shari's lab where Vision lays on a table, while Bruce and Shuri stand over him, and the others watch. Shuri scans the stone, and studies the hologram)

Shuri: Whoa. The structure is polymorphic.

Lincoln: Right, we had to attach each neuron non-sequentially.

Shuri: Why didn't you just reprogram the synapses to work collectively?

Lincoln: I said that…but no one listened.

Bruce: (Staring for a moment) Because, we didn't think of it.

Shuri: (smiling) I'm sure you did your best.

Wanda: Can you do it?

Shuri: Yes, but there are more than two trillion neurons here. One misalignment could cause a cascade of circuit failures. (To T'Challa) It will take time, brother.

Steve: How long?

Shuri: As long as you can give me.

Okoye: (Looking at a device that just alerted her) Something's entered the atmosphere.

(Cut to outside where Sam and Bucky stand, looking up a the sky)

Sam: (Over the comm) Hey, Cap, we got a situation here.

(The defense shield around Wakanda destroys one of the vessels entering the atmosphere)

Bucky: God, I love this place.

Sam: Yeah, don't start celebrating yet, guys. We got more incoming outside the dome.

Vision: (Appearing beside the window with the others) It's too late. We need to destroy the stone now.

Lincoln: (Turning toward Vision) Vision, get your fucking Ass back on the table.

T'Challa: We will hold them off.

Steve: (To Wanda) Wanda, as soon as the stone's out of his head...you blow it to hell.

Wanda: I will.

T'Challa: Evacuate the city. Engage all defense procedures. (He points to Steve) And get this man a shield.
