(scene shifts to Spider-Man and Kamala still fighting Glaive and Midnight)
Proxima Midnight: (pinning down Kamala, who struggles to prevent Midnight from impaling her with her spear) You're strong, little one. But you lack discipline. (suddenly, someone emerges and knocks her away with a large pillar. Midnight recovers and faces a shadowed figure in a large hooded jacket) Who dares...?! (suddenly recognizes the figure) You! (charges towards the shadowed figure, who then uppercuts her to far away. The shadowed figure is revealed to be Carol Danvers / Captain Marvel)
Carol Danvers: (helps Kamala up) Need a help, honey?
Kamala Khan: (amazed) You're...
Carol Danvers: The one and only. Sorry I'm late. I was out for a while... until I heard Secretary Ross' scheme about the Accords protocol went up in smoke.
Kamala Khan: I noticed. It's just... (she hugs her) I'm so glad I could meet you now for the first time. (Danvers chuckles)
Carol Danvers: (chuckles) You're a sweet one. (Midnight recovers; to Kamala) Let's finish this? (Kamala nods and they stand against Midnight)
Proxima Midnight: You should never have come back, Danvers! Now you and that child will die!
Carol Danvers: Yeah? But I don't remember saying you and your big daddy had the right to attack my planet, Midnight. And that makes you and Glaive the invaders. (Midnight snarls and charges at both and the fight continues. Scene cuts to Spider-Man and Glaive still fighting; the fight takes place in a nearby train station, where Peter is joined by Rogers)
Steve Rogers: Looks like you could use a hand, son.
Peter Parker: I really could, Cap. Thanks.
Steve Rogers: Any proper reason you and your friend went to take him on?
Peter Parker: He and that trident witch were attacking my teachers and classmates in school. Still no idea what they meant with this "source" they're looking after.
Steve Rogers: He wouldn't happen to have mentioned anything like a Gauntlet or the Infinity Stone. Would he?
Peter Parker: Little bit. They said they're working for someone called "Thanos". You know anything about it?
Steve Rogers: Well... It's a long story. (Glaive attacks them and they dodge) Which will be hard to tell with this guy wanting to maim us right now.
(they continue fighting Glaive. Just then, Vision arrives to subdue Glaive with Heat Beams from the Mind Stone)
Steve Rogers: Good timing, Vision.
Vision: Request from Mister Stark, Captain. And from the Avengers as well.
(the three stand against Glaive, who then notices the Mind Stone in Vision's head)
Corvus Glaive: Proxima! The keeper of the Mind Stone!
Proxima Midnight: At last!
Corvus Glaive: (to Vision) You have what our master wants, robot. And now you will deliver it to us or we will take your head with it!
Vision: Your master longs for genocide of innocents from this and other worlds. This, I cannot allow to happen.
Proxima Midnight: If you wish to die for the rest of these worms... then let it be done!
(they both fight Vision, who defeats them. Just as Vision turns his back, Glaive recovers and impales him in the back)
Peter and Rogers: Vision! (they stop Glaive and knock him away and help Vision up)
Peter Parker: How could he cut you?
Vision: (weakly) I... don't know.
Kamala Khan: That reaper's glaive. It looks like it can cut through metals more powerful than even Vibranium.
(Midnight and Glaive recover and charge at them, but Danvers blasts them with Star Bolts)
Carol Danvers: Last chance! Withdraw from Earth! Now! (threatening low tone) Don't make me say it twice! (Midnight and Glaive forcibly retreat with teleporters. Then, Danvers addresses to Vision) He's alright. He just needs more time to recover.
Peter Parker: So... what's going on?
(they are all gathered in Wakanda, where Peter and Kamala are talking to Banner, Danvers, Gamora and Strange while Vision's body is fixed by Shuri and Wanda holds his hand worriedly)
Shuri: He won't be out for too long. He'll get back in action soon enough.
Wanda Maximoff: Thank you. (touches Vision's hands) How are you feeling?
Vision: I feel nothing but you. (Wanda smiles)
Peter Parker: So who do they work for again?
Carol Danvers: Only the most vicious tyrant in the whole galaxy. Thanos... (shows a holographic image of Thanos) Former dictator of Titan. He invades planets. He takes what he wants. And wipes out half of a population after doing so.
Bruce Banner: He sent Loki. The attack on New York... That's him.
Kamala Khan: And what's his big deal on Earth?
Gamora: The one reason why he wanted that Stone with Vision even if it meant to rip his head with it. I know. I've known him for my entire life. He ever had one goal: to wipe out half of life in the universe. Once he gets all six Infinity Stones, he'll do so by simply snapping his fingers (snaps her fingers) just like that. And I mean it. Literary.
Peter Parker: Is there any way we can stop him?
Gamora: We couldn't prevent him form getting the Power Stone from Xandar. But at least we can still make sure he won't have the others.
Peter Parker: So... where are those other five Stones?
Doctor Stephen Strange: The Soul Stone as we speak is still in an unknown part of the universe. One of which even Thanos cannot find it. And nor can he obtain it even if he did. Three of them are right here with us now. Space... (shows them the Tesseract in the container) Mind... (points at Vision's head) and Time. (reveals the Time Stone within the Eye of Agamotto)
Peter Parker: Well, that's four Stones. Not counting the one with Thanos by the way. But what about the Reality Stone?
Doctor Stephen Strange: I suppose you saw it. But you didn't know about it.
Peter Parker: I saw it? (a fully recovered Vision appears behind him)
Vision: Allow me... to show you. (puts Peter in a Mind Realm, getting him to remember the moment he and Aunt May were inspecting the artifact they found and merged with the Stone. Peter awakens back to reality)
Peter Parker: Wait. I did. Although it's stuck in there like forever. Like... it's meant to be there.
Doctor Stephen Strange: (thinks for a moment) Ah, yes. The Siege Perilous.
Peter Parker: The "Siege" what?
Doctor Stephen Strange: The Siege Perilous. Another ancient artifact like the Eye of Agamotto. The doorway to worlds parallel to our own. The Reality Stone as you had discovered is the only key to open it.
Peter Parker: Is there any chance we can go through these worlds?
Doctor Stephen Strange: Yes. (sees the Avengers and the Guardians meeting Baron Mordo, Nebula and the surviving members of the Nova Corps) But time for that now is short. We must focus on your current priority... that is Thanos.
(cut to the heroes addressing to the Nova Corps)
Peter Quill: Hey, Irani. Sorry we couldn't help the Corps when Thanos attacked. We were... well...
Nova Prime: You and your fellow Guardians aren't to blame, Peter. We're the ones who should've called for help when Thanos attacked.
Denarian Rhomann Dey: For sure, we though we could handle him ourselves. We were wrong.
Gamora: It matters though that you still have the best of your men. And some of the most innocent of your people.
Nova Prime: Indeed. And it was like they say he does. He only took away half of us. And spared the other half. Although we do wonder for how long the other half will live.
Peter Quill: And we have some bigger advantage. He's still got only one Stone. But probably not for long enough until the Gauntlet is fully unstable. You know what I mean?
Nova Prime: (seeing Parker and Kamala) Yes. I understand. It's happening again. Just like in Attilan. Isn't it?
Nick Fury: (off-screen) You might say so. (comes in) And I also have another plan while we keep this one for contingency. (scene cut to the Avengers and the Guardians preparing for battle) So far, according to one of our spies who received the Collector's message, Thanos is following the order of the Stones he longs to collect: Power, Space, Reality, Soul, Time and Mind. He already has the first one. So we still need to stay ahead of him so that he won't get the Tesseract in time.
(as Fury speaks, Shuri and Stark create a weapon which uses the Tesseract as the core. Then, Stark, Quill, Mantis, Gamora, Drax and Banner gather with Loki, Mordo and Nebula)
Steve Rogers: (voice over) We have what Thanos wants. He's coming to us because of them. And he'll stop at nothing until he gets the last Stone and completes his ultimate goal. But we won't let our guards down until all that we know and hold dear will cease to exist. We will fight. Not for one... but all lives.
(following Rogers' speech above, Scene cuts to him, Rhodes, Danvers, Thor, T'Challa, Nova Prime, Denarian Dey, Fury, Oyoke and Heimdall discussing the battle strategies. The Wakandan armies, the Asgardian warriors, the Nova Corps Soldiers and the Avengers preparing themselves and marching for battle. Peter Parker and Stark having a handshake and Kamala and Danvers sharing a hug)
Heimdall: Thanos may be losing control over the Gauntlet. But until he gets the next Stone, you still need to be prepared, Thor. You'll need a new weapon to stop him. One with the same power that Mjolnir granted you.
Thor: Yes. And I still remember the place.
Peter Quill: (to Gamora, who is staying with the Avengers' army) You sure about this?
Gamora: It's better this way, Peter. If I follow you, he'll have me lead him to the Soul Stone. I'm not saying I don't want to help. I just...
Peter Quill: I understand. But I know everything will be fine. (Gamora smiles and they share a head hug)
Gamora: Just promise me you'll come back alive. Promise me that for your mother. Will you?
Peter Quill: With my heart. I'll be fine. It's you I'm more worried about.
Gamora: (kisses him in the lips) Likewise.
Groot: (shaking hands with Parker) I am Groot. ("Good luck, friend.")
Peter Parker: Same to you, buddy.
Carol Danvers: (to Kamala) I won't be out for too long. I'll just help Thor get his new hammer and then, we'll come back for you. Okay? (Kamala nods) Good. (kisses Kamala's forehead) Wish you best of luck by then, sweetie. (she moves on)
Unknown Voice: (whispering) Kamala... (Kamala overhears the voice, but cannot figure out where it came from)
(scene cuts to Thanos in the Sanctuary II)
Outrider Captain: In a country calling itself "Wakanda", my lord. They appear to be expecting a war.
Thanos: Then let them have war. (the Outrider Captain nods for yes and moves on. He notices Maw with some Chitauri in a Q-Ship) Where are you going?
Ebony Maw: My apologies if you are unannounced of this, father. But if I heard correctly from one of our watchers, there are rumors that Thor Odinson and some of his comrades may be setting course to the Asgardian Dwarves of Nidavellir.
Thanos: Nidavellir? (pauses and understands) He seeks a new weapon to replace Mjolnir. Go. He must not complete it. (Maw nods and goes on. Thanos stares at Earth chuckling diabolically) Prepare yourselves as hard as you can, heroes. But I will obtain those Stones. One way or another. (Midnight approaches)
Proxima Midnight: I have received a message. It is said that Nebula is with some of Gamora's comrades on Titan. With the Tesseract. (Thanos is alarmed to hear this) I will send our troopers.
Thanos: No.
Proxima Midnight: (confused) Father?
Thanos: You and the others go to Earth. As for the Tesseract and its keepers on Titan... (holds his fist with the Gauntlet as the Power Stone ignites light; dark tone) I'll do it myself.
