Following last season's almighty cliffhanger, Grey's Anatomy returns to US screens with a two-hour double bill on September 25. The first two episodes of the new run, titled 'Good Mourning' and 'Goodbye', pick up from the moment season regulars George O'Malley (T.R. Knight) and Izzie Stevens (Katherine Heigl) flatlined, prompting their colleagues to pull together in an attempt to save their lives.

Here, DS presents a gallery of cast shots recently released by ABC to promote the new season. For those not wishing to know who lives and who dies, we advise not to think too much about who's missing from the lineup.
