Grey’s Anatomy: Revisiting Constance Zimmer’s character

As mentioned before, Constance Zimmer played the role of Dr. Alana Cahill in five episodes of Grey’s Anatomy season 9. Zimmer’s Alana was a physician advisor who came in to save the hospital from financial ruin. At the time the hospital was named Seattle Grace-Mercy West. 

After the hospital got involved in a plane crash scenario, it needed to fight for its survival. Alana’s suggestions put every staff on edge as they needed to reach out of their comfort zones. 

Her story arc on Grey’s Anatomy started with her disguised as a patient waiting in the ER. She intended to dig out the problems in the hospital’s functioning. Since she needed to wait in the ER for 45 minutes and noted that, she started on the wrong foot with the rest of the staff.

She came in as an advocate of closing down the ER to redirect funds to the rest of the hospital. Her goal was to invite funds from a corporation named Pegasus which offered cash on condition. Secrets about Alana soon started coming out. Although in the past she was Richard’s student, a choking up incident at the surgery pushed her out of active medical practice and she became an advisor.

Soon, an emergency needed Alana to do a surgery at the ER proving the need of the department. However, the doctors were left shaken when Alana revealed that Pegasus would fund the hospital only if it did not have an ER. 

Feeling cornered the doctors tried various methods, from mass resignations to secret planning to buy the hospital themselves. While empathetic towards the doctors, Alana was seen as the mediator between Pegasus and its cut-throat stipulations, and the staff’s self-sabotaging ideas.

After Catherine and the Harper Avery Foundation stepped in to the fund the hospital, Seattle Grace-Mercy West became Grey Sloan Memorial Hospital and was saved from Pegasus. Zimmer’s Alana Cahill was not seen on Grey’s Anatomy since. While the hospital’s safe condition was not Alana’s doing, the good change may not have happened if she had not come in.
