After reviewing Joan's last calls and the time they arrived there, they were able to deduce one thing: Joan had not gone to see Jordi and Bernat in Vilanova before going there. They had spoken to them on the phone and an hour later they were at Raquel's Masía. With the speed they were in, they had probably gone directly from wherever the hell they were. That was the time it could take from Barcelona to get there.
In all likelihood, those idiots would go out to eat and drink from the farmhouse and in the afternoon they would go to see the two henchmen with diarrhea who were in the emergency room in Vilanova. They decided to do the following to be able to incriminate Joan: Xavier compressed all the information into files, he even uploaded the heaviest videos to Joan's cloud space. From the mobile phone they had access to their email and all their networks.
