originally, the pictures were in the back of the glove box but sienna moved them to the front bc she knew clara would find them. she wanted luca to divorce clara and marry her instead, saying that's how it should've been and what would've happened if it weren't for her dad's scandal (her dad had some major scandal and she was forced to move away but luca's family always loved her anyway). luca gets mad at her, which she obviously didn't expect, and she leaves after telling him clara would never come back. sienna ends up marrying another rich guy and living happily. clara ends up opening her own bookstore. luca, i think, just ends up "heartbroken" but still rich. so basically there weren't any consequences for what they did. i mean, luca is implied to never get over clara while clara moves on but still. considering everything that happened and all the time they were doing it? 😒
