Lubna Gourion guest starred in this episode. She is a French actress known for playing the main character in the Disney Channel France Original Series Mère et Fille (Mother and Daughter), which also aired in Italy as Mamma e Figlia.
She recorded her part in French and was later dubbed to Italian by Deborah Morese.
Dubs of her lines in the rest of the languages were made from Italian, not French. This is proved, for example, when she puts her hand on Alex's arm after meeting him: she originally said "un petit conseil, accroche-toi" (a little advice, work hard) but was dubbed to "preparati, ne avrai bisogno" (get ready, you'll need it) in Italian and the rest of the dubs say this latter sentence instead.
It is a curious fact that the Argentine dubber of Emma, Malena Oriolo, also dubbed Lubna in both Alex & Co. and Mère et fille. This is not a problem since Emma and Lubna don't meet in the series.
In Rebecca's dream, she gets replaced by a girl called Lucrezia (The same name of the actress who portrays Linda, by the way), who says "Totally!", which is later revealed to be her sister Giada's, catchphrase in Season 3.
This episode is titled "Reason or feelings" in France and "An ending" in Brazil.
