List of Dexter characters
After the police uncover DVDs of the men torturing and raping female victims, Dexter switches Lumen's DVD with a blank DVD, which he scratches in order to avoid suspicion as to why it was blank. Lumen then acknowledges that she knows what a risk he is taking by being with her, and tells him that he has been her only way through the experience. Lumen proves instrumental in getting information from Emily Birch, the first victim of Chase's team and the only other known survivor. Tilden is Lumen's first kill, as Dexter allows her to make the killing blow at her request. The two then return to Dexter's apartment, where they have sex.
