Dr. Morgan Reznick is a resident at St. Bonaventure Hospital. Morgan is revealed to be a former avid archer. Morgan has an arrogant and competitive personality that drives the other doctors crazy, but as time goes on she begins to lose some of this, particularly after Morgan makes a mistake that costs a patient her arm. Melendez subsequently compares Morgan's relationship with Shaun Murphy to that of himself and Dr. Lim during their own residency and suggests that their differing ways of approaching situations can be complimentary. During "Quarantine" Morgan is revealed to be forming a romantic relationship with an EMT named Tyler. After Tyler falls ill from a deadly virus that quarantines the ER, Morgan works to treat him and is visibly devastated when he dies of the virus despite her best efforts. In "Quarantine: Part Two," Morgan treats Lim for the virus while determining that it is not airborne and that Tyler contracted it due to a ripped mask and bodily fluid contact. Thanks to Morgan's efforts and use of extracorporeal membrane oxygenation as a treatment, Lim survives. After quarantine ends, a devastated Morgan watches as the CDC takes away Tyler's body.
