Mitchell was devastated to accept the fact that Sarah was the mastermind of the murder of Della Hernandez – his ex-fiancé. He didn't think he had a murderer in his house. Even more painful, he made her the queen of his household. Even without love. Because Sarah had trapped herself in a pseudo-marriage.
Her biological mother's sobs were heard in the car that would take them home. The two of them probably never thought that their daughter-in-law was willing to kill Della just because of revenge and blind jealousy. Sarah did not think that what she did had hurt everyone's feelings, including their two children.
Meanwhile, Mitchell's biological father could only pensive stare at the rain-soaked road through the windshield of the car that would take them back to his residence. Everyone was lost in their own thoughts, and hoped that everything they heard was a dream. Then, tomorrow morning, everything will change.
