In the Avengers Facility..
Scott is explaining where he is during the battle of Wakanda and he is also explauning what is the Quartum Realm and how the five years that passed felt like five hours during the Quartum Realm.
But suddenly,VEGA's voice came over yhe speakers of the facility and said,'Quartum Realm,interesting!'and Steve Rodgers said,'Wait a minute,you and that Doomguy is listening the whole time!?'It responded him with,'Yes,we do.'then Scott asked,'Where's that voice coming from?and who's Doomguy?'But his question was ignored as Steve asked VEGA,'What do you two know of the Quartum Realm?'It responded him with,'The UAC originally duscovered it by shrinking a camera in the size of an atom and ee recorded the footage of the realm,the results had been..surprising.'Natasha asked,'How surprising?'VEGA responded by saying,'The UAC kept the camera inside for ten years and the project was aboneded in flavor of the argent energy project and not until recently,the camera had been extracted and the ten years of footage lasted ten hours in the recording,and so the UAC had a theory,is that time was slowed down in the Quartum Realm and so the ten years of footage only lasted ten hours.'And Scott breaks the conversation and said,'So that's why the five years inside felt like five hours.Steve asked,'Could we possibly reverse engineneer it and use it to travel back in time?'VEGA responded him with,'Yes,it is possible,but we need some furthur reserch.','So there is a way to save everyone.'Scott disrupted them with,'Guys,you still hadn't explained to me that what happened in these past few years!'
In Tony Stark's house...
Tony Stark was taking care of his daughter,and she went into the garage and there,she found her mother's Iron Man armour,and he explained to her what it is and that when she grows up,ahe might get one,but that was interrupped by Steve and Natasha walking towards him and Tony said to his daughter,'Honey,I need you to stay here and let daddy do the talking.'And then the two Avengers talk to him about the plan
So your plan is to time travel back in time before Thanos can get all the stone.'Steve responded with,'Pretty much.',Tony responded with,'I gonna have to say no to that.'Natasha asked him,'Why?we could bring back possibly everyone.'
'And give up,all this?Look,I thought I told you I gave up on the Avengers and I can't just give up all this for a plan that could possibly fail.'And Steve disappointed,'Well,I respect your decision.'And they went back to the facilty.
Meanwhile at a diner in New York...
Bruce Banner,which has basically fused himself with the hulk,is having his breakfast and taking pictures with his fans,with Scott and Rhodey trying to conveniece him to join them in their plan,Rhodey explained the plan and Scott talked about the Quartum Realm and how time works there and how VEGA told the Avengers that the Slayer was a demon slayer.
'So your telling me that we could travel back in time and save everyone and that demons acutally exist and that Doom Slayer dude that came outta nowhere was a demon slaying badass?'Bruce exclaimed,'Yes and that AI he was with?he apprantly knew about the Quartum Realm and how it works,we just need a genius to figure out how to reverse-engineer it and use it to our adventage!Like you!'and Bruce responded with,'Ok,I can take a look,see if that insane plan of yours could acutully work.'
Back at the Facility...
Steve said,'Well,we tried conveince Tony,and it didn't work,how about you?'Rhodey said,'Well,we did found Bruce though.And apperently,he fused him with the Hulk.'But Bruce said,'Well,I can't figure it out,it's too complicated,even for me and the AI,we can found Tony though.'But Natasha responded him with,'No way,he said that he quitted and wouldn't help us anymore.''That's understandable,considering now that he has a family.'But Rocket Racoon said ,'What about Thor?he's a god after all and we hadn't seen him ever since we killed Thanos.'Steve said,'That's a good idea,and you two,why don't you bring Bruce and Doomguy to New Asgard as well.','Sure,I can handle the 'big scary slayer'.Rocket Racoon joked.and then,they used a Land Rover to carry the Avengers and The Doom Slayer rode a prototype combat bike from SHIELD's unused vehicle base.
New Asgard
After a long trip to the mountains,they finally saw a snall town by the name of New Asgard,inhabited by the survivors of the raid on Asgardens ship,and while traveling in town and asking people where Thor is,Bruce saw Valkyire and asked her if she knew where Thor is.
'Thor?Yeah,he has changed a quite lot since the last time you guys saw him,he is in that house over there,but beware,he changed,but not in a good way.'Well,thanks Valk.'Bruce said,followed by the Doom Slayer raising his two thumbs at her,she laughed and said,'Who is him?He's quite funny,a new guy?'Rhodey said,'Well,we'll explain later.And again,thanks again.'
And they went to Thor's house and instead being greeted by Thor,they were greeted by Korg,and then he knew their resquest to talk to Thor and then,Thor shouted,'Who the hell was that,Korg?',Korg answered in his quiet voice saying,'It's your old friends,Thor!'And then he came out of his room.
And boy,how the might Thor has fallen!
