April Kepner joined the series during Grey's Anatomy Season 6 Episode 5, and she officially became a series regular in Grey's Anatomy Season 7. April will depart the series on Grey's Anatomy Season 14 Episode 24.
April came onto the scene as one of the rival Mercy West residents. Mercy West was Seattle Grace's competition until the two hospitals merged and ushered in a plethora of new doctors.
Jackson Avery is the only remaining, and living, Mercy Wester outside of April.
April was perky, and annoying to many, but she eventually grew on everyone and became one of the fiercest, gifted doctors of the hospital. Under Owen's tutelage, she became a Trauma goddess and honed her skills in the specialty.
She overcame many obstacles and tragedies, and at no point did it dull that brightness she inherently carries.
