So basically what happened after I officially ended this is this.

My own character (interdimensionalPortaller / iP) got an account, some boring stuff happened post-Portal 2, such as Portal: Prelude Convention etc.

iP then got in a dialogue with the Chell that is actually canon to Portal 2, empatheticAmazon / eA, which went down like this:

IP: ...
EA: {{Okay, that may work.}}
IP: ((Stress on MAY))
EA: {{Um.}}
IP: Moron kernelsprite, huh?
IP: Still better than that brown girl aspiring to take over the world.
EA: Yes, but that's fixed at this point.
EA: Wait, what?
IP: (Link to combineOverseer's Formspring)
EA: Okay then.
EA: Anyway. Looks like he's going to start some exposition now that he's not a moron.
IP: Who?
EA: My sprite.
EA: Wheatley. He was a core, this robot thing, built specifically to be an idiot in order to make another one stop murdering us
EA: I'll give you the full story later.
IP: Oh that Wheatley?
EA: You know him?
IP: Probably?
IP: ((I can explain))
EA: Okay. So how?
IP: ((This character is SUPPOSED to be Chell, but I decided to write up a story for Portal 2 before Portal 2 and got 90% of things wrong))
EA: {{Okay.}}
EA: Eh, never mind. It's irrelevant now.
IP: (( (Link to Portal 2: The Stupidest Sequel of All Time) ))
IP: What is irrelevant?
IP: That metal ball?
EA: How you know him.
IP: That.
EA: It'll just make everything far more confusing than it needs to be.
IP: He was in Aperture Laboratories.
EA: In any case, I still don't know where I am or what I'm doing here.
EA: Hang on, whaaat? You were there?
IP: Yeah, and?
EA: I thought there was some kind of alternate universe thing going on here. You know what, that actually explains it.
IP: Explains what?
IP: That you're playing Sburb?
EA: How you know him. You probably know alternate universe him or something.
IP: Alternate universe what?
IP: Wheatley?
EA: Yes.
EA: What's your name, anyway?
IP: Assuming our knowledge about Wheatley is different, yes.
IP: You can call me "Ms. Johnson-Rattmann".
IP: That author calls me that
EA: Wait, what? What?
EA: Is your first name Chell?
IP: Yes.
IP: And?
EA: Oh my god.
IP: Wait did you say that?
EA: You are me.
EA: What the hell is going on here?
IP: You weren't in Portal:Access All Areas, were you?
IP: Hence, you are not me.
EA: Okay, but...I guess I just need to get used to this alternate universe stuff.
EA: Because I'm talking to me from another dimension, evidently.
EA: (If I'm wrong, please correct me)
EA: But in any case, I am, and I have no idea what I should say here.
IP: Probably?
IP: I have figured out some of time travel stuff, but alternate universe me?
EA: I don't know.
EA: Well, let's see how far our lives have been the same.
EA: When they diverge.
EA: Just speak up when I say something you didn't do, okay?
IP: Okay.
EA: So.
EA: I'll just start at the testing, because I'm not sure what happened beforehand at this point.
EA: I woke up from stasis to hear GLaDOS talking to me.
IP: Yes,
EA: Went through 19 test chambers, found a few back areas where Doug drew on the walls.
IP: Okay, the same,
EA: She tried to throw me into an incinerator, so I escaped and eventually ended up killing her.
EA: I was thrown out of the facility, then dragged back inside...
IP: Yes.
EA: ...put into stasis for the next 300 years, only waking up once in between.
IP: Three hundred?
EA: Wheatley then entered my relaxation chamber and got us out of there.
EA: Yes, I think.
IP: I quite remember it was until 2107.
EA: Huh. So that's probably where it diverged.
IP: But then, yes, I remembered that Wheatley did the same.
IP: Sort of.
EA: Sort of?
IP: Points of divergence work like small changes, growing over time.
IP: I think.
EA: I wouldn't know. What are you in charge of in your session, anyway?
IP: What "my" session?
EA: Because if it's alternate dimensions, then that would be helpful.
EA: Oh yeah, the whole all sessions thing.
IP: It isn't really "mine",
EA: ?
IP: I'm not really PLAYING SBURB, you know?
IP: I'm just in the Incipisphere, where I'm sure it's the other session than yours.
EA: I thought you were.
IP: No, I wasn't.
EA: Oh...so you tagged along with another player, or what?
IP: Once I woke up in a room with yellow walls
EA: Okay...
IP: And some half-recognizable voice told me she wanted to get rid of me and get me into "a mod".
IP: And I said that I'm going to "Portal:Access All Areas".
EA: Hmm. Odd.
IP: And it turned out that that Portal:Access All Areas was stranded in the Incipisphere.
IP: It was in a session all along.
EA: Which, if I'm understanding Wheatley's cryptic blather, is where I am right now. Or one of them, anyway.
IP: Different sessions.
IP: Different Skaian systems.
EA: Hmm.
EA: I'll have to go soon.
IP: Okay.
IP: Any chance we will talk again?
EA: I hope.
IP: Goodbye.

[06:38] EA: Oh. Hello.
[06:38] IP: Hi.
[06:38] IP: Where we stopped?
[06:38] EA: I'm not sure.
[06:38] IP: Something with Skaian systems.
[06:38] EA: Augh, hold on.
[06:39] EA: Sorry, more of those fucking skeletons tried to sneak up on me.
[06:39] EA: I'm doing this quest thing for these consorts.
[06:40] EA: Augh, again. Okay.
[06:40] EA: I think that's it. So. Skaian systems.
[06:40] IP: Different sessions.
[06:41] EA: Yes. So I assume that means different mediums, different Skaias, different everything.
[06:41] IP: Yes.
[06:41] IP: As far as I've figured out, "my" session has three planets.
[06:42] IP: One greenish black, one bright yellow-orange and one brown-gray.
[06:42] EA: Okay.
[06:42] EA: Besides the bright gold one I keep waking up on.
[06:43] IP: That goofball with a chained moon?
[06:43] EA: Yeah, it's been happening for a while. Thought it was just normal weird dreams.
[06:43] EA: But apparently it's real.
[06:44] EA: I think I've heard that whoever's in charge of space wakes up early. Wasn't sure what that meant until just now.
[06:44] EA: Augh, ogres. Can't catch a break here. Just a minute.
[06:45] EA: Okay, I'm back.
[06:46] IP: And what are these dreams like besides living on a golden planet?
[06:47] EA: Well, there are these people that look like they have white shells or something
[06:47] EA: And once there was this eclipse or something.
[06:48] IP: How are you sure they are people?
[06:48] EA: Where it went into where I can only assume is Skaia.
[06:49] EA: I don't know. We have talked.
[06:49] EA: Oh, and I can fly too. Almost forgot that bit.
[06:49] EA: In the dreams, I mean.
[06:49] IP: Why fly when there is the portal gun?
[06:49] EA: That's not the point.
[06:49] EA: The point is, well, I can.
[06:50] IP: Hmm.
[06:51] EA: So, I'm guessing it's standard for the _ of Space to start having those dreams early.
[06:51] EA: From the little bit I've learned, anyway.
[06:52] EA: Oh crap, I have to go!
[06:52] EA: Bye!

[01:55] IP: So what?
[01:55] EA: I don't know, honestly.
[01:55] EA: I'm still figuring things out here.
[01:55] IP: Litlle busy with the quests for your consorts?
[01:56] EA: Well, that's over with.
[01:56] EA: But I'm still trying to figure out some stuff.
[01:56] EA: Found some ruins a little earlier, I'm looking around in there.
[01:56] IP: Well,
[01:56] IP: I am quite literally LIVING in some ruins.
[01:57] EA: Hmm.
[01:57] IP: Look like a test chamber.
[01:57] EA: Interesting.
[01:57] IP: With boxes and buttons.
[01:57] EA: Although I guess I should have expected it.
[01:58] IP: And I don't know for how long these were abandoned, but for sure longer than three hundred years.
[01:58] EA: Hmm. Is the post-apocalypse pre-recording thing working?
[01:58] IP: Nah.
[01:58] EA: Oh.
[01:58] IP: The technology isn't even as advanced as Aperture's
[01:58] IP: .
[01:59] EA: So...it's something else?
[01:59] IP: Yeah.
[01:59] EA: Oh, I think I know.
[01:59] IP: A Communist civilization.
[01:59] EA: That's not what I had in mind, but hey. Plausible considering what else has happened in the last day.
[01:59] IP: What was that?
[02:00] EA: Just, you know, entering Sburb and things like that.
[02:00] EA: Sorry if it was unclear.
[02:01] IP: What was?
[02:01] EA: The "things that have happened in the last day" thing.
[02:02] IP: You never told me anything about entering, you know.
[02:02] EA: I am not good at this, am I?
[02:02] EA: *shrug* I'm just not good at this conversation stuff.
[02:02] EA: Which is very sad, considering I'm talking to essentially me right now.
[02:02] IP: Essentially.
[02:02] IP: The experiences are still different.
[02:03] EA: Yeah, you do have a point.
[02:03] IP: So.
[02:03] IP: First of all, is this "entering" related to Sburb?
[02:04] EA: Yes.
[02:04] EA: I'm in a session, apparently as the Rogue of Space.
[02:04] EA: Still trying to figure out exactly what that means for me, but oh well.
[02:05] EA: I'm exploring these ruins I found in my land, and I'm discovering a few things.
[02:05] IP: These other ruins of what?
[02:05] EA: Agh, crap. Something just came up.
[02:05] EA: Again.
[02:05] EA: I have to go.
[02:06] EA: I'm not sure what they're of, but...I still have to go. Now.
[02:06] EA: Talk to you later.

There were also several logs at Formspring, but one thing worth mentioning is that both of these females got the frog temple language figured out.

And then I decided I can't beat a dead horse over and over and over and announced a Portal: The 4th Millennium franchise "sunset."

And that's where it ended.
