Marco: are you sure it's a good idea that you meet a creature that is possibly more powerful than we'll that dream demon guy?
Dipper: ah I'm sure it'll be fine, besides we gotta hurry don't we? By fixing the mess that your friend and Bill did to the multiverse we managed to barely push it back
???: yeah but that's not the only thing you fixed
Dipper: ya got a problem with that Eyepatch?
Morty: do I have a problem?! What do you think?! By fixing the multiverse after it all collide together you didn't just fix both your multiverse but you also fix MY multiverse!! All the plan and effort I made just falls to the ground!!
Dipper: it had to be done, by capturing multiple version of yourselves than assassinating your grandfather than blame it on his other timelines, your multiverse too cause a chain of madness! And it probably was what created that thing in the first place, look I don't care how munch you hate your old man but at least try to understand what is going on in that man's head, you seen it before, you just don't understand it
Morty: tsk yeah like what? I spent many... Many crazy experiments with him, and he didn't gives 2 fucks about me! I'm nothing but a experiment!
Dipper: yeah well not anymore, thats the whole reason we let you join in! So you can escape from  whatever you were thinking in that head of yours! Besides! I remove whatever crazy things he did inside you haven't I? Your fine, so get over it
Marco: ok that's enough you 2, were not really that far into the woods so we shouldn't be out and about shouting our problems like this
Dipper: nah relax Nachos, people here still have a brain cell the size of a peanut, they'll think we're just talking about video games and that shit
Marco: right... I guess that's how they were so oblivious to the fact there's monsters and mysteries all over this place
Dipper: yup, I'm quite a multitasker if I do say so myself, having to plan to seperate your whole entire universe collide mess faaaaaar away from Gravity falls was more harder than I thought, than hiding and seperating them just by these woods and forest was more difficult
Marco: I know, I can't believe you did all this by using a deal with a demon
Dipper: yeah well I was originally planning to change things to fix it but something else got in the way... And I used it to my advantage
Marco: huh?
Dipper: nothing, I'll go meet the giant salamander now, wish me luck

Narrator:

Dipper puts his hands in his pocket than walks into the woods, when hes in deep enough that's when Bill came right out of the shadow of the trees

Dipper: what? Want to visit the big guy with me?
Bill: no, ugh I might as well die the moment he saw me in this... State
Dipper: suit yourself
Bill: I wouldn't so boldly walk into his dimension asking about something with my power if I were you, if anything he might do some pretty interesting things, it be pretty boring if I can't see it for myself but I still rather not to
Dipper: man if your scared of him just say so
Bill: I am not scared of a .... A x o l o t l
Dipper: is it necessary for you to... Spell his name out?
Bill: what? He might show up if I say it normally
Dipper: relax im the 1 who have your power not him
Bill: exactly that's the problem! I be in shame of myself for the next malenia if he finds out a human put me threw this
Dipper: geez it's like losing your powers made you lose your entertaining side
Bill: Im still entertaining! I just know everything bcz I see it! Not anymore!!
Dipper: do you remember what I told you what that salamander told me?
Bill: the poem?
Dipper: specifically "he'll have to invoke my name, one way to absolve his crime, a different form a different time" when you invoke his name in grunkle Stan's mind he did grant your wish, in doing so send you to this universe where things did not go as it supposed to, people from many other worlds mainly the bad ending ones somehow were thrown into a portal to gather in a void, we were the bad results of a story, the alternative route if we made a bad decision, we had no idea why it even happens but we practically become good friends with each other and started as a gang, they had the great idea to call themselves "The bad end friends" sounds kinda lazy and boring but it'll have to do
Bill: pfft- it sounds childish
Dipper: what did you expect? Anyways, as I am supposed to be what if you took over me completely, and this body yes it does has pieces of your power in it, but than you know that whole glitchy creature thing happen so I had that great idea to turn back time, go to when I face you off and trick you into making a deal with me
Bill: ugh I hate this part
Dipper: than I was supposed to only fix maybe a few things but suddenly the power of the Axolotl came and bring you here so I took advantage of it and repair all our world's
Bill: ok now that's even worse!! You used his powers the moment he brought me here?!
Dipper: whaaat? It was the only shot I got, it's not like I have a choice
Bill: I don't care but as soon as you step in there your good as gone
Dipper: eh I'm willing to take that risk
