It seems this is the end to an adventure that kept us in suspense for so long. Actress Esther Acebo, who played Stockholm, expressed her love for the series in a photo of her and her loyal companion Denver with the following touching message:‘After the chaos… silence. It’s official. I’ve finished shooting @lacasadepapel. Thank you to @jaimelorentelo for being on this amazing journey with me. THANK YOU to my whole family for this incredible adventure.’Unfortunately, the beautiful blonde isn’t the only one to write such moving messages. Luka Peros who played Marseille also posted a photo on Instagram looking grief-stricken, with Darko Peric, Helsinki, with the simple ‘Boom Boom Ciao’ in the caption, a popular catchphrase from the third season.Touching farewellsPedro Alonso who played Berlin kept it simple and classy, just like his character, by posting a photo with the caption ‘Bye bye Berlin’. And then it was the famous Professor’s turn, Álvaro Morte, to say his farewell to his character and the whole series family by toasting them and all their fans.‘I’m toasting everyone, the team […] and all of you who watched us across the planet. Thanks to all of you… Live long!’We still have no concrete information about whether the fourth part of Money Heist will really be the final season - but we do know it's set to air on Netflix in January 2020, just four short months away. Could it really be the end or just the end for these particular characters?
