Dexter didn't actually remember what Carolina had instructed him to do. Because he was really not aware that all the actions he did were only because of Carolina's intent and purpose, to control all of her property that she had.
Dexter also didn't know how to get out of the shackles Carolina had created for him. But indeed he was also not aware of what Carolina had done to him, which was something he hated. At that time, at that time, when the full moon of the following month arrived, Dexter who turned into a werewolf, did not realize when he made Carolina who was nearby, fell down.
Because he completely lost his mind, when he transformed into a complete werewolf. Dexter, he really didn't know that when he woke up, he saw that Carolina had fallen on the ground, and was covered in blood. Because when he became a werewolf, he had knocked the Carolina over the dressing table, which was near his bed, at that time.
