From David, something deep down told you that they were hiding something but what were supposed to be just suspicions little by little became more evident. You had arranged to meet Simón to see him at his house and everything seemed to be going well but David arrived at Simón's house beaten and more so in the face (it was common for David to get into street fights), while supporting Simón who was healing his wounds.
