Luis Arreglo is a character who appears in the official Lost novelization Endangered Species by Cathy Hapka. He is a university professor of biology from England, and Faith Harrington's advisor. He sells out to Q Corp, an infamous corporation known for its pollution. He is presumably killed by Faith's boyfriend Oscar Wolfe after being injected with venom of the snake called Death Adder.
