Final answer:
The provided text does not provide clear information about John or Alice or any promise that may have been made between them. Relevant characters are not featured.
Step-by-step explanation:
Based on the information provided, it's not clear what John makes Alice promise him after this incident. The text refers to characters named Alcée Laballière, Clarisse, Bobinôt, Bibi, Eliza, and Calixta, but doesn't mention a John or Alice. Therefore, without additional context, it's impossible to define what John makes Alice promise him after this incident. It's essential for any subject, especially when studying literature, to have all the necessary details available to accurately understand and interpret the text.
