Episode 30 is the seventeenth and penultimate episode of Season 2 of Alex & Co. and the 31th episode overall. It premiered in Italy on November 22, 2015.
The scene where Alex apologizes with Nicole with posters was shot two times, one with the posters in Italian and other in English.
Due to an editing mistake, in the English version the poster "13 years ago we met" is first shown in English, then changes to Italian and then is back to English. This error is known to have happened in all countries where English posters were used, except Spain and Latin America. The Disney+ version doesn't have this error.
However, in Germany and Portugal posters were shown in Italian.
This episode is titled "Reconciliation" in France and "A forgiveness" in Brazil.
