It’s been an interesting first season and it’s coming to an end for “Hawthorne”.

“Richmond Trinity Hospital’s Chief Nursing Officer Christina Hawthorne loves her job, despite the long days and nights she spends on the hospital’s front lines. She does everything possible to help her patients and defend her staff, even if that means violating protocol or taking on doctors or administrators who sometimes lose sight of a hospital’s true purpose. But her intense focus at work comes with a cost to her personal life, now that she’s a single mother — her husband recently lost a battle with cancer — trying to raise a rebellious teenage daughter.”

So what will the season finale bring us?

Check out this sneak peek:

Christina struggles with the reality that she may lose her close friend David, whose cancer has returned. But she hopes to wrangle him a spot in a new clinical trial, one that Tom has already promised to another patient. Isabel tries to get Bobbies leg back after selling it on the street. Kelly has a difficult time saying goodbye to a longtime patient. Camille spends the day in Amandas world as part of a school project. And Candy floors Ray with some big news.

The finale, aptly titled “Hello and Goodbye,” airs tonight, Tuesday, August 18 @ 9/8c on TNT.
