Once upon a time, Ink City had a Rapunzel and a Flynn Rider. They adopted an orphan girl, and lived happily... until all three disappeared without a trace. Much later, a new Rapunzel appeared... and the original Flynn returned. Their reunion is bittersweet, as this Rapunzel was still in the middle of her first great adventure with him... and wasn't aware of everything that was supposed to come after that point.
Flynn: There is an upside of all this... It's not everyone who gets the chance to fall in love all over again, now, is it?
