So far, on Nurse Jackie, viewers have fallen in love with Edie Falco as Jackie and Merritt Wever as Zoey.

However, over the next handful of episodes, the Showtime hit will shine a spotlight on another staff member of of All-Saints Hospital: Eve Best's Dr. O'Hara.

According to E! Online, the icy doctor's life isn't as carefree as her nonchalant manner would have fans believe. Why is she seemingly so uncaring toward, well, everyone? Look for a personal crisis to be revealed, one that provides Best with incredible material.

Nurse Jackie viewers will soon see a side to Dr. O'Hara that involves more than just eating at expensive restaurants.
