S1·E6 Luciferous

As an unsure Marian considers withdrawing from the Others, she moves into a new apartment that harbors a vague yet sinister force hiding in the wallpaper intent on scaring her enough to ignore her supernatural gift, but she is more concerned to learn that some of the Others appear to be stalking her. Meanwhile, Mark is tormented by the responsibility of his empathic abilities and can find relief only in the arms of Satori, but they are prevented from becoming physically intimate because proximity causes their environment to explode.
