When Max hands Rapunzel the Corona law handbook, there's a dagger driven through it. It's the same dagger one of the Stabbington brothers stabbed Eugene with in Peril on the High Seas (2019), but the handbook he carried in the inside pocket of his vest took the blow instead and saved him.
When Rapunzel brings her parents to the Snuggly Ducking, she says the same thing Eugene said when he first brought her there: 'Garçon! Your finest table, please.'
