Alex McAliister is Natalie’s father. He is in his mid-forties and is a widower. Not much is known about him, but he seems to be of an easygoing nature. He has a step-son named Max in college, who is from his wife’s previous marriage before he married Nat’s mom, Carla. Mr. McAllister knows of Satan’s and Nat’s relationship, but he believes Satan to be “Stan,” a short, dark haired freshman who she tutors. Mr. McAllister encourages Stan to see him as a father figure and treats the boy like one of his own kids.

Alex is a former alcoholic (developed from his wife’s death), works as a biology professor, and volunteers often at their church.
