Mark's sister.
Devon is sarcastic, intelligent, and laid-back. Her rationality and subdued character have led some fans to dub her "the only normal character on the show." She is supportive to her friends and family, especially to her brother Mark, to whom she is the closest friend after the death of his wife. They both exude exhausted introversion and enjoy witty banter together, but Devon once confided that he could "depress" her.
She wants to help Mark uncover the secrets of Lumon.
