Cricket Marlowe is a medium who stems from the uptown district of New Orleans and claims to have worked several times with the FBI in cases of missing children. His "gift" manifested for the first time when he was nine years old, finding the keys lost by his "nana."
Personality and Appearance
A man of short stature, dressed entirely in black with a white helmet haircut. Eccentric and with behaviors that border on a sham, Cricket is a man who knows how to use flow-talking to his advantage. He is homosexual.
Cricket Marlowe walks into the Miller's house and says he is able to find Flora, Lee's daughter. He taps around a bit before finding Flora's hideout which is hiding a bonnet. Cricket then tells Lee that Flora is alive and with Priscilla. Later on, Cricket conducts a "ritual" to summon someone from the other side. Shelby, Matt and Lee all join in a circle. This is where he is able to talk to "The Butcher", revealing to be one of the ghosts of the Lost Colony. Cricket then tells the Millers that he can find Flora... for $25,000. Mad at him, Matt tells him to get out of his house because he believes that Cricket is a fraud and was faking the whole time. Before he leaves though, Cricket whispers to Lee about her oldest daughter, Emily.
Lee visits Cricket the next day and convinces him to come back to the house to find Flora. While at the house Cricket comes face to face with the Roanoke colony and of course, The Butcher. He says if they give up Flora, the Millers will move out. 
The medium returns to Roanoke House to offer his support to the Millers, but after having trouble concentrating, he decides to get his wits together by taking a walk through the woods. While on his walk, he has a close encounter with the mysterious woman of the woods who, after temporarily blinding him with a mysterious powder, reveals part of the true story of the Lost Colony. Headed to the hotel to retrieve some ingredients for a spell, Cricket's flirtation with an Uber driver is interrupted by Flora who runs in front of the car. While chasing her in the woods, Cricket is captured by the Butcher and her acolytes, only to be later painfully disemboweled by Ambrose White and the Lost Colony as a sacrifice to the Old Gods, after his gut was sliced open with a cleaver by the Butcher under the horrified gaze of Matt and Shelby. 
Cricket was a gifted medium.
