[[WMG: AustinAndAlly will crossover with Series/LivAndMaddie.]]
Actually, Laura Marano was taped in a yet to be aired episode of Liv and Maddie, although it's unlikely she'll reprise her role as Ally Dawson in this episode.
* Jossed, Laura's role in that episode (Howl-A-Rooney) is a girl raised by wolves named Emmy "Fangs" Wulfert, who helps Liv do better to get the role on a movie Liv was auditioning for.

[[WMG: The Sonic Boom makes most of its money off of Austin and Dez (and most recently {{Jessie}}) on the "You Break It, You Buy It" policy]]
Seriously, Austin and Dez are ''always'' breaking things. And the fact that Jessie works for a loaded family means that the Sonic Boom shouldn't have to worry about losses for a ''long'' time.

[[WMG: The real life siblings of the 1st 3 main characters will appear in a future episode either separately or together.]]
Think about it- this is a great episode idea. this ends up with these people coming:
* Austin's cousins Arnold, Arthur, Ashley and Andrew (rest of R5, That would be Riker, Rocky, Rydel and Ellington Ratliff respectively)
* Ally's big sister Bay (Vanessa Marano, references to ''Series/SwitchedAtBirth'' would be inevitable, perhaps an [[PlotTailoredToTheParty [=Eigen=] Plot]] where sign language skills come in handy). Bonus points if Katie Leclerc reprises her role as Daphne to drive the homage further.
** Fic idea: New Sound & No Sound: Austin want to try out a new style of music, but Dez ruined it by making some equipment go haywire and rendered him (even maybe everyone but Ally) temporarily deaf. Bay (and maybe Daphne) chimes in and teaches everyone ASL so that they can still live, somehow. The episode will be very similar to an episode of Series/SwitchedAtBirth.
* Trish's little brother Matt (Rico Rodriguez, Just like Vanessa, references to ''Series/ModernFamily'' would be inevitable)
These people end up being the DistaffCounterpart to Team Austin. In the end both parties will reconcile. Other plots can happen if they end up being recurring.
** Confirmed, Rydel cameos as an Austin Moon fangirl in season 3.

[[WMG: The show's universe is actually an alternate reality of the ''Franchise/SailorMoon'' universe...]]
...in which the concept of Sailor Senshi is nonexistant.

In this reality's Silver Millennium, Queen Serenity had a son rather than a daughter, and there was a Sun Kingdom ruled by Queen Metallia, who, despite being amorphous, had a human daughter around the same age as the Moon Prince. There was a long-lasting rivalry between the Moon and Sun Kingdoms, so those from the Moon Kingdom never crossed paths with those of the Sun Kingdom and vice-versa, until the Moon Prince and Sun Princess met by chance and slowly developed a forbidden friendship, meeting from time to time at the Moon Kingdom without their parents' knowledge. When Queen Metallia found out about this, she was so blind with rage that she possessed a peasant woman named Beryl, who raised up the people of the Sun Kingdom in a war against the Moon, with the same consequences we all know.

Before dying, Queen Serenity sent her son and the Sun Princess for rebirth on Earth during the 21st century, in which they're reborn as Austin and Ally, picking up several traits from their past lifes. For example, the Moon Prince loved to sing, but had very little musical talent; to make up for this, when he is reincarnated as Austin, he gains the talent he always wanted in his past life. Also, Ally [[CharacterTics chewing her hair when she's nervous]] is actually something the Sun Princess used to do, albeit Metallia didn't let her, as it wasn't very ladylike of her part.

Additionally, the Moon Prince and Sun Princess aren't the only ones that underwent rebirth. The prince's man-in-waiting and the princess' lady-in-waiting, who were the only ones who knew about the forbidden friendship, were reincarnated, respectively, as Dez and Trish. Also, Dallas is the reincarnation of a servant boy the Sun Princess had a crush on, and Kira is the reincarnation of a princess of the stars who was the Moon Prince's fiancée.
* This needs to be a fanfic. It needs to.

[[WMG: There will be a ShoutOut to ''Series/EveryWitchWay'']]
Both are KidCom series about teenagers in Miami, but a crossover isn't possible since one's Disney and the other's Nick. But something on the sly, like the other school's team name being mentioned on a background poster, is a different story...

[[WMG: Austin Moon is a fictional reincarnation of [[Music/{{Carpenters}} Karen Carpenter]].]]
If you look at it closely, Karen and Austin's roles in their groups are similar- both of them are singers, and their 2nd half are songwriters/composers (Richard and Ally respectively, Except that Ally is not his sister though, and Ally gets a chance to sing by late season 2). Also,

[[WMG: The show is inspired by the Carpenters, but sitcom wise, or is a parody of the Carpenters without the sibling connection.]]
The creators of the show might have gotten the idea after doing a little research about the Carpenters (if they did), and decided to make one that only the old viewers can understand said reference.
** He's a GenderFlip of ''Series/HannahMontana'' without the PaperThinDisguises.

[[WMG: Better Together's lyrics refer to each member of Team Austin (or Team Austin itself).]]
