Now that I've put this together, I realize this might seem like a "rarr Equestria Girls sucks" kind of fandom meta-joke, and that's not the intent here. The joke here rests solely on the gag of "Going back to HIGH SCHOOL?? Please, give us back the cosmic horrors from beyond the edge of reality, anything but this!!"
Transcript:Rainbow Dash: Alright alright, fine. I fly back out of Zombieville…
Discord GM: Once you cross the edge of town and turn around, you see Ponyville in its "true" topsy-turvy self!
Applejack: So yer gonna tell us in-character what you saw, right–
Rainbow Dash: I fly back in!
DM: This time, you see the outskirts become a grid before you. Giant dice litter the horizon in all directions. Life-sized paper figurines charge towards battle.
Rainbow Dash: Nope, too meta. I loop around and do it again.
DM: Ponyville seems to be under the tyrannical rule of an army of sentient apples.
Applejack: Come on!
Rainbow Dash: Okay, okay, I've seen enough.
Twilight Sparkle: What happens if I try going into town?
Discord GM: Do you have an in-character reason to do so?
Twilight Sparkle: To figure out why Rainbow's going back and forth?
DM: You suddenly morph into a gangly two-legged creature. Ponyville becomes a concrete suburban grid, and you stand before a lavish high school.
Fluttershy: Oh NO!!
Rainbow Dash: Oh great.
Pinkie Pie: But why tho??
Rarity: Get out get out get out!
Twilight Sparkle: Worst timeline, worst timeline!
DM: Uh… okay.
