I swear, there are at least three different Disney songs I could associate to this AU and it's GREAT. Though speaking of Disney, I can see Xiaolang either seeing the outfits Sakura's regained or remembering them in his own regains, and like... assuming she was some sort of princess in their past life (and since he has a sword, that might have made him her knight, and them mentioning it to Fai and Fai being like 8'''')

alternately, someone making this joke to some extent
