Jordana is the woman that runs Great White Shark, a museum about an alleged shark that plagued the nearby beaches. She gives a long, rambling history of the shark, which she claims she hunted down and killed "two months ago". Said history is the plot of Jaws and it's not clear if she's conning people or is demented; she does mention "that little snot Richard Dreyfuss decides that it was all his big game".
There are giant billboards for Great White Shark all over the main road, so Jordana appears to have some money.
Her name is given in the MTV flipbook "Guestward Ho!".
