This is how Into the Changeling Timeline goes in Sci-Ryan's and Clay's Time Travel Adventure.
[Ryan, Sci-Ryan, Clay and the gang landed on the map from Twilight's castle and arrive in Equestria]
Ex-Terminator: What happened? Explain! Explain?
Evil Anna: Uhh. Sci-Ryan?
Ex-Terminator: Evil Anna? Are you an... EQUESTRIAN SIREN?!
Evil Anna: I think so. [to Sci-Ryan] I think I have no idea what you are.
Sci-Ryan: What do you mean?
[Sci-Ryan looks at his arms and saw that his hands are hooves]
Sci-Ryan: AAAAAAHHHHH!!!! What happened to me!? Did Rothbart did this?!
Thomas: I don't think so.
Sci-Ryan: Oh. [sighs] What... does the rest of me look like?
Ryan F-Freeman: Well, Sci-Ryan. You look like you. Only not you. Uh, your nose is rather big.
Sci-Ryan: My nose?!
[Sci-Ryan puts his hoof on his nose and is about to scream]
Sci-Twi: [covers his mouth] Are you going to scream again?
[Sci-Ryan looks at a photo of Queen Chrysalis and Ryan as a changeling king]
Sci-Ryan: Ryan? You might want to have a look.
[Ryan looks at the photo]
Thomas: Ryan? Is that you in this photo?
Sci-Ryan: How come you're on four legs, Ryan?
[Ryan whispers to Sci-Ryan's ear]
Sci-Ryan: Whoa. Wait, why are you a changeling in that photo and why is Chrysalis next to you?
Ryan F-Freeman: I don't know, Sci-Ryan. Can you walk?
[Sci-Ryan nods and easily manages to walk on all four legs]
Crash Bandicoot: What happened to you, Sci-Ryan?
Sci-Ryan: I'm a pony, Crash. My girlfriend is so happy.
[Evil Anna nods]
Matau T. Monkey: What's happened to us, Bertram?
Bertram T. Monkey: I'm an Equestrian Siren and you're a pony.
Ryan F-Freeman: What about me?
Twilight Sparkle: I think you're an alicorn like me.
Ryan F-Freeman: Cool. Let's hope Pinkie Pie and Fluttershy don't mistake us as changelings.
Thomas: Well, this whole place now looks like the changelings themselves own it.
Evil Ryan: Yeah. This photo has Ryan as a king of the changelings and I don't know what I am.
[They look at their surroundings and see that Canterlot castle now has changeling-like features]
Evil Ryan: We should find Zicora first.
[Ryan nods then saw spears pointing at Ryan and his friends]
Ryan F-Freeman: Fluttershy! Pinkie Pie! I'm happy you found us.
Pinkie Pie: Silence, changeling.
Evil Ryan: Wait. Did she say "Changeling"?!
Pinkie Pie: Yes.
[Thomas looks at Fluttershy and Henry, in Trainbot form, lands behind her]
Ex-Terminator: What are you pointing those sticks at us?
Henry: Those are spears, robo-changeling.
Fluttershy: Didn't you ever go to spelling school?
Ex-Terminator: I'm a Dalek, not a changeling!
Henry: All servants of Queen Chrysalis and her husband found in these wood must be...
Thomas: Let me guess, exterminated?
Sci-Ryan: [gulp] Yes.
Ex-Terminator: Yeah. [to Pinkie Pie] You don't understand. I'm a Dalek. My friends are not changelings!
Pinkie Pie: A likely story! Do something Dalekish!
[Ex-Terminator fires at a ladybird on a tree]
Pinkie Pie: Cool shot.
Sci-Ryan: Nice shot.
[Matau claps his hooves]
Fluttershy: The servants of Chrysalis and Chrystalize will do anything to save their evil skins!
Ryan F-Freeman: What are you talking about?
Zecora: Stop! If they are changelings we'll soon see. Though I think they're not what they appear to be.
Ex-Terminator: Who is the talking zebra?
Ryan F-Freeman: Zecora! Please, listen to me.
Crash Bandicoot: Wait. Let her use the green goo.
Zecora: Beneath this salve, no changeling hides, for it reveals the truth inside.
[Zecora paints Ryan and the gang in green sap. Then, they glow showing that they're not changelings]
Crash Bandicoot: Wow. I'm glowing!
Henry: What does it mean?
Zecora: The meaning is far worse, I see, for it is we who should not be.
Ryan F-Freeman: That means we're not changelings. [to Zecora] I can tell you everything, Zecora.
Zecora: I'm sure you can, Ryan, but let's not talk here. Chrysalis and her army will soon draw near.
[They go into the woods]
Ryan F-Freeman: So, Zecora. What happened here and am I with you?
Zecora: Afraid not, techo-pony, for the you in this timeline is dead. Only the you you've become is way over his head.
Crash Bandicoot: I suppose the me in this timeline has blood of the Doctor in him?
[Then Crash saw another Crash Bandicoot in his 2nd Doctor form]
Thomas: Hello. Who are you?
[Crash goes to his Doctor counterpart]
Crash Bandicoot: Hi, fella. I'm Crash. Crash Bandicoot.
[Then Crash in his 2nd Doctor form looks at Crash]
Crash Bandicoot: Is that me?
[Thomas nods and Crash wonders what the 2nd Doctor version of Crash is called]
2nd Crash Bandicoot: I'm Doctor Crash, bandicoot.
Crash Bandicoot: Wow.
Doctor Crash: Nice shoes. Watch this.
[Doctor Crash removes his nose then his nose sprouts legs and starts running around Crash]
Doctor Crash: Don't Chrysalis hate it when her nose runs? [laughs]
[Then Doctor Crash's nose comes back on his face]
Crash Bandicoot: You seeing this, Zecora?
Zecora: From the way I see is not Discord. But this bandicoot is a Time Lord.
Ryan F-Freeman: Yeah. How did the changelings take over Equestria?
Zecora: The changelings took over not long ago. Though I'll wager in your world that isn't so.
[Doctor Crash nods]
Ryan F-Freeman: Chrysalis and her husband tried to take over Canterlot but me and my friends stopped them.
Doctor Crash: I escaped after Chrysalis changed Ryan into a changeling. I injected myself with the blood of the Doctor.
Evil Anna: I saw a note and the back of the photo.
Ryan F-Freeman: So the me I became is now what?
Evil Anna: Changeling. How do you feel as a pony, Sci-Ryan?
Doctor Crash: If me and my friends don't stop Chrysalis and her boyfriend, we would've be in a fine pickle, won't we?
Crash Bandicoot: Doctor? You think I act like your 2nd incarnation?
12th Doctor: No. You do act like me in this timeline.
Doctor Crash: I think I need to tell you something. I am not made. I am born a Time Lord.
Evil Ryan: Wow. What happened to you and me, Sci-Ryan? And what's with a horn on your head?
Sci-Ryan: What horn?
