(scene shifts to Wakanda, where Vision and Doctor Strange sense something)
Vision: He's here. He's coming.
Kamala Khan: What does that mean? (Vision does not answer and Kamala acts hopeless)
(scene cuts to Thanos, who arrives via the Space Stone teleport gate)
Gamora: (shocked) No...!
Carol Danvers: Steve? That's him. That's Thanos.
Steve Rogers: (to Peter) No matter what happens to us. Stay with her (Kamala Khan). And don't leave her alone. (Peter nods and rushes for Kamala)
(Thanos unleashes more Chitauri and Outriders to fight the Avengers while he himself faces Thor)
Peter Parker: Kamala! (finds Kamala laying on her knees) Kamala... (approaches her)
Kamala Khan: Peter... (she hugs him and starts sobbing)
Peter Parker: It's alright, Kamala. I'm here. I'm here for you. (a tear slides from his eye in his face)
Kamala Khan: (sees the Avengers in battle) So this is it?
Peter Parker: I don't know. But if it is...
(Peter shows her the locket he made for her. She opens the locket and sees a red ruby heart. In tears of joy, she hugs him. Scene briefly shifts to the Reality Stone igniting again. It then shifts briefly to the Mind Stone in Vision's head and the Time Stone in the Eye of Agamotto (all igniting at the same level) as Vision and Strange sense it. Thanos also senses something happening as the Stones with him start to ignite)
Steve Rogers: (noticing the reaction) It's happening.
Natasha Romanoff: Just like Gamora predicted.
Kamala Khan: (with a smile) If only I had time to tell what I felt for you... ever since I saw you for the first time...
Peter Parker: Well... (puts his hand on Kamala's cheek) we still have time.
(with tears sliding in their faces, they share a kiss as a wind blows around them. Scene shifts to the Infinity Stones in the Siege Perilous, Vision's head, the Eye of Agamotto and the Infinity Gauntlet igniting even harder light)
Thanos: (grunts as the Gauntlet is affected by the Stones' reaction) H-how...? Why is this still happening? (screams in agony as the Stones continue igniting until the Gauntlet begins to crack in the holes meant for the Mind, Reality and Time Stones. Thanos gasps as he remembers the first Gauntlet's destruction in Attilan) No...! It can't be...! (sees Peter and Kamala embracing each other; furious) NOOO! (rushes towards the two, who notice him and fight back)
Peter Parker: The Gauntlet is breaking apart. We can still end this.
Kamala Khan: Are we together?
Peter Parker: (holds her hand) Together. (Kamala smiles and they continue fighting Thanos and, after overpowering him, hold on the Gauntlet)
Groot: (holds Thanos' right arm to prevent him from punching the two) I am Groot! ("I got you!")
Steve Rogers: We have to hold him off! (he lassoes Thanos' arm with his Gauntlets' grappling hooks while Danvers and Gamora hold on Thanos' neck to restrain him)
(Peter and Kamala notice a large crack in the middle of the Gauntlet and begin to reopen it further)
Thanos: (struggling) No! You can't do this to me! Stop! Don't...! NOOO! (Peter and Kamala successfully rip the Gauntlet apart, causing an sonic boom explosion which knocks everyone else away. Peter recovers first and approaches Kamala)
Peter Parker: Kamala? (she recovers in Peter's arms)
Kamala Khan: Did we... did we win?
(the others recover and see the Gauntlet shattered into pieces and the Power and Space Stones flying away)
Peter Parker: I think so... we did. (Kamala smiles and shares a head hug with him)
Thanos: (recovers and sees the Gauntlet completely destroyed) No...! (the Gauntlet's shards disintegrate to dust. Then, he sees Peter and Kamala and grins furiously. Thanos gets up to charge at them until Thor suddenly appears in front of him and impales his chest with the axe-piece of Stormbreaker. Thanos lays down on his knees slowly succumbing) (weakly) Why... why can't you understand... my reason to gather them?
Thor: I carefully understand. You believed that there were too many of us... to live in this entire universe. But eliminating one half of it... do you really think this is going to re-balance all? In my travels around the universe, I've seen many things. Most of them are opposite to each other. But... they're still secure. Because... this is the true balance in the universe. The very will of the universe itself.
Thanos: If what you say is true... (looks around) Then, perhaps I never really was unlike your kind. I was just one more of them. After all this time. How can you live with this?
Thor: We find a way. A better way.
Thanos: And I will respectfully... accept... my fate. (Thor removes Stormbreaker from Thanos' chest as Thanos slowly lands down on his back and collapses into ash)
Thor: (Gamora approaches him) I'm sorry.
Gamora: Don't be. A part of him knew this day would come.
(they notice the remaining Chitauri and Outriders disintegrating into ashes one by one)
Doctor Strange: It's done.
(scene cuts to Vision and Wanda embracing passionately. Back on Titan, Mantis is embracing Hulk until they feel something)
Mantis: Something is happening... (a drop of water falls on her face; it is raining)
Peter Quill: There hasn't been rain in this planet since... (they see the Power Stone descending from the air and digging through the center of the planet. Plants begins to regrow) (smiles) ... well, well... things are starting to get beautiful.
Mantis: (smiles) I can feel it. Life. (tears of joy slide in from her eyes and she feels the wind blowing)
Nebula: That means... (referring to Thanos) ...at last. He's gone. It's over.
Hulk: So... (to Stark) ...did we win?
Tony Stark: (he has a vision of Peter and Kamala kissing; smiles) Yes... we did.
