Ryan Keely says: "She's from the Garth Ennis comic book, Preacher. She's another woman who is excellent with a gun. She and her man, an Irish vampire, have a fantastic road trip where they fight God and Satan and blow up a lot of stuff. She stands by her man and her man stands by her. Tulip and Jesse are two people who are truly in love. I've always wanted life to be like an early '90s road trip movie and that comic book really solidified what I think romance should be like."
