Early in the show's first episode, Elliot takes the subway after ruining the life of the owner of Ron's Coffeeshop. Elliot is paranoid, thinking he's being watched. And he's right! One of the passengers on the train is Sam Esmail, the creator of the show, who made a cameo Alfred Hitchcock style. But he wasn't done with that. Esmail made an appearance later in the season, when Elliot was looking in the mirror and saw several different characters in his trademark hoodie. One of those was Esmail.
