On March 25 ... a doctor ... haunted by his past ...

... does it hold a key to the future... or will it destroy his career?

In case you haven't seen the promo or couldn't guess, Dr. Owen Hunt's traumatic past is front and center when Grey's Anatomy returns a week from Thursday. The tagline above tells it all.

Kevin McKidd teased the return of Owen's PTSD last month, but to what extent will it impact his future, both as a doctor and possibly with Cristina? It will be very interesting to see play out.

When Teddy's patient seeks to end treatment, and therefore her life, she turns to Hunt for help. The situation triggers Hunt's memories of his life at war - and his relationship with Teddy.

Meanwhile, Callie and Arizona may be a model couple now, but they have a difference in opinion on what the future holds. Finally, ousted chief Richard tries to adjust to his role as a surgeon.

We'll have sneak preview clips, episode stills and Grey's Anatomy spoilers up for you as soon as we come across anything, as always. For now, here's ABC's promo of "Suicide is Painless" ...
