Headscratchers / My Little Pony: Equestria Girls – Sunset's Backstage Pass

• Why didn't they pony up this special? In Rollercoaster of Friendship, they admitted it was unnecessary narratively but needed to promote the toys. So why not here?
  • Maybe the toys in question are old enough it's no longer a priority.
  • Maybe the production staff finally put their feet down and said "No, we're not gonna shoehorn in a "Pony Up" if it's not necessary."
• So, the Dazzlings said that they looped a vocal track in order to properly sing... how exactly does that work? I'm really confused, they seemed to be singing in real time...
  • They pre-recorded the song, auto-tuned it so it wasn't horrendous like their singing at the end of "Rainbow Rocks" was, set up a speaker to play it during the concert, then lip-synced it a la Big Mac in "Filli Vanilli".
• Why would K-Lo and Su-Z toss Sunset and Pinkie instruments during the final concert? While the two are good musicians, they have no way of knowing that.
  • The Rainbooms have done enough gigs by now they may be recognized.
• In the time loop where Sunset and Pinkie bring the security guard a cat in order to get past him and to the Dazzlings' trailer, how come they didn't get the rest of the Rainbooms to help them? Considering Sci-Twi, Rainbow Dash, Applejack, Rarity, and Fluttershy were willing to believe Sunset on the time loop in the previous ones and the previous time loop even helping the duo find clues about the Dazzlings' seemingly having involvement in the time loop, why couldn't Sunset and Pinkie get the other five to help them out in that time loop? After all, seven heads are better than two. Pinkie getting distracted wouldn't even be a problem if the other five Rainbooms were helping as well for investigating the Dazzlings' trailer.
