In 2014, on the Sanctuary II.
2014 Thanos: (to Ebony Maw) Run diagnostics. Show me her memory file.
2014 Ebony Maw: Sire, the file appears entangled. It was a memory, but not hers. There's another consciousness sharing her network. Another Nebula.
2014 Thanos: Impossible.
2014 Ebony Maw: This duplicate carries a time stamp... from nine years in the future.
2014 Thanos: Where is this other Nebula?
2014 Ebony Maw: In our solar system. On Morag.
2014 Thanos: Can you access her?
2014 Ebony Maw: Yes. The two are linked.
2014 Thanos: Search the duplicate's memories for Infinity Stones.
[Memory of the meeting with all the Avengers starts playing]
Bruce: And these stones have been in a lot of different places throughout history.
Tony: Our history. So, not a lot of convenient spots to just drop in.
Clint: Which means we have to pick our targets.
Tony: Correct.
[End memory.]
2014 Thanos: Freeze image.
2014 Gamora: Terrans.
2014 Thanos: Avengers. Unruly wretches. What's that reflection? Amplify this, Maw.
2014 Gamora: [Looking at a reflection of present Nebula] I don't understand. Two Nebulas.
2014 Thanos: No. The same Nebula. From two different times. Set course for Morag. Scan the duplicate's memories. I want to see everything.
Asgard, 2013
Outside the Asgardian Palace, Silver is floating around for an entry for Jet and Rocket to sneak into Jane's chambers while she is napping. Meanwhile, Mikey stands guard for the residents of the palace if they come by.
Jet: I was wondering if this palace has some unique treasures around here somewhere!
Rocket: Okay, greenie, let's focus on the mission, shall we?!
Jet nods.
Inside the palace.
Mikey: I'm in position the hallways are now clear. But Jane is in the right where you guys are entering.
Silver: I think I see an opening from right over there!
Jet: Hmm! I wonder what Thor's doing!?
Rocket: We don't know!
Back to the halls of the palace.
Frigga: My ladies, I'll see you after. Go on ahead.
Thor tries not to get caught behind a large post. However, she finds him hiding behind a column. But Thor gets shocked when he sees his mother behind him.
Frigga: (sees her son from the future) What are you doing?
Thor: Aah!
Frigga: Aah!
Thor: OH, God!
Frigga: Oh, God! You're better off leaving the sneaking to your brother.
Thor: No, I wasn't sneaking. I was just going for a walk.
Frigga: (noticing Thor's clothes) What are you wearing?
Thor: I always wear this. It's one of my favorites.
Frigga puts her hand on Thor's face and takes a good look at him before looking at his right eye.
Frigga: What's wrong with your eye?
Thor: Oh, my eye. Remember the, uh Battle of Harokin when I got hit in the face with a broadsword?
Frigga: You're not the Thor I know at all, are you?
Thor: [Pretending] Yes, I am.
Frigga: The future hasn't been kind to you, has it?
Thor: I didn't say I was from the future.
Frigga: I was raised by witches, boy. I see with more than eyes, and you know that.
[Thor attempts to hold back his tears and fails miserably.]
Thor: [voice breaking up] Yeah, I'm totally from the future.
Frigga: Yes, you are, honey.
Thor: I really need to talk to you.
Frigga: We can talk.
[They both hug each other.]
Somewhere in one of the palace's chambers, Jane wakes up before getting up from the couch, but Rocket and Jet close in on her. Silver looks on from a nearby window telling them to take out the Reality Stone from Jane.
Silver: (whispers in a soft voice) Okay, do it.
Rocket and Jet both nod before emerging from behind the couch in order to get the Aether from the woman.
Jet: Here we go!
Rocket: NOW!
Jane: (turns around, looking scared) Oh, my God! What are you two doing in here!
Jet: We're here to extract the Reality Stone from your body.
Rocket: At least I have the stone extractor to get that thing out of you.
Jane: (screaming) GO AWAY! LEAVE ME ALONE!
She starts to throw pillows at them before Silver uses his psychokinesis to freeze her in place.
Silver: Okay, now, Rocket!
He does just as he puts the point of the extractor in Jane's butt before sucking out the Reality Stone.
Jet: Come on, let's go!
They leave the room to rejoin Mikey at the doorway in order to find Thor.
Michelangelo: Hurry! We gotta get out of here and find Thor.
The trio rejoin the turtle in orange before running to find the God of Thunder until Jane calls the guards to pursue Rocket, Jet, Silver, and Mikey.
Jane: Guards! Guards!
The Asgardian Einherjar arrive at the scene of the crime.
Guard #1: What is it, Midgardian woman?
Jane: These creatures just came into my room and took out the Aether from me!
Guard #2: There they are I see them!
Silver: (sees the Einherjar coming toward them) I think we have company.
Jet: (hops on his Extreme Gear) Come on!
Rocket gets on Mikey's shoulder, while Jet and Silver and hovering in the air. They began escaping from the soldiers.
Rocket: Thor! We got it!
Michelangelo: Dude, where are you?
Silver: We need to get out of here now!
Jet: Right this way!
Guard #3: Get that rabbit!
Guard #4: And these other creatures!
Meanwhile, in a room, where Thor and Frigga chat about the upcoming event.
Thor: Mom, I have to tell you something.
Frigga: No, son. You don't. You're here to repair your future, not mine.
Thor: But this is about your future.
Frigga: Uh, it's none of my business.
Suddenly, Rocket, Jet, Silver and Mikey burst into the room.
Michelangelo: There you are, Thor.
Silver: We've been looking all over for you.
Rocket: Hey. You must be Mom.
Jet: And fast as well.
Rocket: I got the thing. Come on, we got to move.
Thor: Oh, I wish we had more time.
Frigga: No, this was a gift. And you're going to be the man you're meant to be.
Thor: I love you, Mom.
Frigga: I love you. And eat a salad.
Rocket: Come on. We gotta go. Three... two...
Thor: No, wait!
He holds out his hand.
Michelangelo: Uh, what are you doing?
Rocket: What am I looking at?
Jet: You'll see!
Silver: I think we're about to find out.
Frigga: Oh, sometimes it takes a second.
Thor summons the 2013 version of his original weapon, Mjølnir.
Thor: (delightful) I'm still worthy.
Michelangelo, Silver & Jet: Ooh! Awesome!
Rocket: Oh, boy.
As Rocket activates his, Silver, Jet, Mikey and Thor's Advance Tech Suits.
Thor: Goodbye, Mom.
Frigga: [whispers] Goodbye.
Moments later, they return to the present with the Reality Stone along with Mjølnir.
This event takes place on the day of the Sacking of Asgard and the death of Frigga, which actually upsets Thor that he lost his mother because of the leader of the Dark Elves, Malekith, who interrogates Frigga about the whereabouts of the Aether before she got stabbed by Kurse during the Second Dark Elf Conflict.
