Grey's Anatomy returns a week from Thursday with an all-new episode, and the emotional stakes will be raised once again with Teddy still in the dark about Henry. Who will tell her and when? How will she react?

Meanwhile, the body count may be rising as a severe car crash involving an entire family results in an all-hands-on-deck situation in the ER, leaving the eldest daughter to make the toughest decision of her life.

Lexie finds herself working alongside Mark's new girlfriend, Julia, during an eye surgery, setting up exchanges that should be awkward to say the least (see our photo gallery for images of Mark and his new love).

As Teddy calls upon Cristina to help with her patient in the O.R., one wonders if she will learn about her husband's tragic demise under the worst possible circumstances. You can almost feel the tension in the air.

How do you predict this will play out? Watch ABC's first promo for "Suddenly" and comment below:
