The word "werewolf" is used three times in the movie: once in a news report Gavin is watching online, once spoken by Eric, and the very last line of the movie as spoken by Gavin.

When Gavin is shaving himself of his hair, the last thing he shaves is his left eyebrow, but in the next, cut-to scene when he starts looking up into the mirror, the eyebrow is unshaven, and the same for when he starts screaming into the mirror in the next shot.
