Things have taken a turn for the worst on Sin Tu Mirada as Isauro manages to prove that he is the father of Marina's son, Rafael. Marina was sure that Alberto was Rafael's father but a DNA test was able to prove otherwise.Isauro managed to prove that he is Rafael's father by switching his DNA samples with those of Alberto and hence manipulated the DNA test to his favor. This now gives him rights over Marina's son after the judge ruled that he was allowed to see Rafael as his father.The situation has left Marina, Ricardo and Alberto dejected as Isauro seeks to use this outcome to his advantage and win over Marina. His plan is to take Rafael away from Marina so that she is forced to end her relationship with Ricardo and be with him.Do you think Isauro's schemes will eventually make Marina choose to be with him?
