One male character has romantic and sexual feelings for each of his two half-sisters, both before he knows that they are his half-sisters (the first is played out in season 1, and the second in season 3). The same character experiences sexual tension with his estranged mother in season 1. S1E5: a teenage character is getting a blow job from a middle-aged adult woman. S1E7: a fairly graphic rape scene is shown on screen, with the woman begging for the man to stop and the man ignoring her. S1E8: during a dream sequence, a character is groped by the naked image of his mother and shows physical repulsion. S1E13: flashbacks to a mind control rape between half-brother and sister. SPOILERS: The first of these incestuous relationships is the result of vampiric mind control: the half-brother and sister involved are not aware of what is happening/in control of their actions.
