STAGE TUBE: Sneak Peek - Meredith Recieves Long-Awaited News on ABC's GREY'S ANATOMY

On Thursday night's upcoming episode of ABC's GREY'S ANATOMY, entitled "Dark Was the Night",  Teddy puts her husband's life in the hands of her peers when Henry is sent to the OR for surgery and she's called away on another case; Meredith and Derek receive the long-awaited news about Zola; Callie and Jackson come under fire when their patient experiences post-surgery complications; and Meredith and Alex are involved in a life-threatening situation when they travel to a neighboring hospital to tend to a sick newborn.

Considered one of the great dramas of our time and recipient of the 2007 Golden Globe Award for Best Drama Television Series and multiple Emmy nominations, including Outstanding Drama Series, "Grey's Anatomy" returns to ABC for its eighth season.

Meredith, Cristina, Alex, Jackson and April have all reached their 5th year as residents. In a year that can make or break a surgical career, the residents are tasked with their first-ever solo surgeries, no longer under their attendings' direct supervision in the O.R.

Torn apart by Meredith's well-intentioned but devastatingly harmful interference in Derek's Alzheimer's clinical trial, Meredith and Derek are living apart. Their relationship hangs in the balance, as does the fate of their newly adopted daughter, Zola.

Cristina and Owen's wedded bliss is in jeopardy when they can't agree on whether or not to have a baby. When Cristina becomes unexpectedly pregnant and decides to terminate the pregnancy, Owen is against it, leading to the biggest issue in their relationship thus far. Meanwhile Meredith and Cristina, the best of friends, find themselves at the center of each other's worlds once again, as their marriages are tested.

Leading the 5th year residents is newly-appointed Chief Resident April Kepner. Her position of authority is immediately tested by her skeptical peers. Meanwhile Jackson, who is consistently proving he has the skills to be a very talented surgeon, is extremely happy in a new relationship with Lexie. And doing his best to move forward after his relationship with Lexie has ended is Mark Sloan, who has become a loving parent to daughter Sofia with the now-married Callie and Arizona.

Love abounds in other places in the hospital, as Bailey's relationship with Nurse Eli continues to grow and Teddy falls deeper in love with her patient, Henry. Richard Webber focuses on caring for his beloved wife, Adele, who has Alzheimer's disease.

Seattle Grace Hospital is a place where life isn't lived in the black and white, but in the shades of grey.
