- "F**kin' bitch!"
- ―Casey's last words[src]
Casey was a free-spirited wiccan on the HBO original series True Blood. Played by American guest starring actress Fiona Dourif, Casey makes her debut on the episode "She's Not There", at the beginning of the series' fourth season. A member of the powerful witch Marnie Stonebrook's Coven, Casey plays a recurring role through the same season, and met an untimely demise in the Season 4 episode "Soul of Fire".
At the next meeting the witches buzz what they've achieved. Someone asks Marnie what they're going to bring back next, and with a twisted smile on her face, Marnie answers that they're going to bring back a person. The coven is shocked and Tara Thornton decides she's going to wait outside.
Eric Northman arrives at the coven's meeting and asks Marnie to identify herself. She steps forward and Eric politely thanks her. He informs her that the coven is disbanded, adding: "Before you think of agreeing and meeting behind my back, know this: There is no behind my back."
Marnie asks what's in it for her, and Eric grows angry. Lafayette Reynolds tells her that Eric does not negotiate, and urges Marnie to accept. Tara comes inside to see what's going on and seeing Eric there, she groans, "I hate this place."
Marnie considers for a moment, then quickly says, "Join hands." But Eric is faster. He grabs Marnie and sinks his fangs into her neck. Horrified, Holly begins to lead the coven in chanting a protection spell. Everyone joins hands but Lafayette, who is too scared to participate. Tara runs up behind Eric with a stake. Eric quickly throws Marnie down and seizes Tara by the neck. He smiles. "What have we here?"
Seeing Tara in danger, Lafayette joins the circle, and Marnie rises off of the floor as the room goes dark. She is possessed by a spirit and chants an incantation in Latin. Eric drops Tara and suddenly looks very afraid. His fangs retract, his gaze goes blank, and he flees the magic shop. ("You Smell Like Dinner")
Marnie Stonebrook awakens unable to remember cursing Eric. Lafayette tells the coven that they need to make amends, or Eric will kill them all for what they have done. The coven members decide that they need to fight back to preserve their freedom of religion. ("If You Love Me, Why Am I Dyin'?")
Casey agrees to help Marnie/Antonia in her attempt to extinguish the vampire race. She introduces her boyfriend Trevor to the coven as they gather at the Moon Goddess Emporium. They cast a spell intended to summon all nearby vampires to meet the sun. ("Cold Grey Light of Dawn")
At the Moon Goddess Emporium, the coven yells at Marnie/Antonia because she brought Eric back with her. She tells them that he is under her control. Tara is angry at her for rejecting Bill's peace offering and causing needless violence. Marnie tries to make them hold hands to cast a protection spell. When they refuse, she plots her next move against the vampires and orders the others not to leave. Tara and Holly have misgivings. Marnie brings Eric and Roy, her most loyal follower, with her to the "Festival of Tolerance" and leaves the rest of the coven trapped by a spell. ("Let's Get Out of Here")
At Moon Goddess Emporium, Casey and the other Witches discuss the lack of phone reception, still trying to escape captivity. Meanwhile, Tara and Holly are hatching a plan to undo Martonia’s spell. Martonia barges in and the witches say that she can't keep them prisoner. She ignores their protests. Jesus Velasquez is able to break through the protective barrier and says that he wants to help Marnie. Tara and Holly chant a ritual to break the protection spell. They run outside to Sookie Stackhouse and Lafayette. Just as they are reunited Marnie transports them all back inside. ("Burning Down the House")
All of the witches are terrified when the store is besieged by vampires except for Marnie. She calmly insists that her spell will protect them and jokes about the situation. Her attitude causes Casey to get mad and attack her. Marnie, defending herself, flings a knife at her magically, killing her. Jesus Velasquez lied to Marnie about helping the already dead Casey, and secretly used her blood in a ritual to free Antonia's spirit from Marnie's binding spell. Marnie convinces the coven to follow her lead out of fear and attempts to kill the vampires that are attacking them with a spell. The witches are freed from her control when Lafayette and Jesus manage to separate Antonia's spirit from her. Marnie is killed by vampires but Sookie Stackhouse convinces them to spare the rest of the coven. ("Soul of Fire")
- According to Casey, she only began practicing witchcraft to piss off her parents. ("Let's Get Out of Here")
- Trevor is Casey's boyfriend, and she convinced him to join Marnie's coven mainly for the necromancy spell.
