When it comes to Grey's Anatomy spoilers, a little scoopbit goes a long way. So enjoy the following just-released-minutes-ago ABC teaser for Grey's Sept. 28 episode, followed by a list of the regular and guest casts.

"I Am a Tree": Cristina meets Burke's parents ? and in the most awkward of circumstances, the interns campaign for Izzie's reinstatement to the surgical-intern program, plus Addison takes a break from her hospital duties, and a surgical patient lives what may be her last day to the fullest.

This program will repeat Friday, September 29, from 8-9 pm/ET.

Grey's Anatomy stars Ellen Pompeo as Meredith Grey, Patrick Dempsey as Derek Shepherd, Sandra Oh as Cristina Yang, Isaiah Washington as Preston Burke, Katherine Heigl as Isobel "Izzie" Stevens, Justin Chambers as Alex Karev, T.R. Knight as George O'Malley, Chandra Wilson as Miranda Bailey, James Pickens Jr. as Richard Webber, Kate Walsh as Addison Shepherd and Sara Ramirez as Callie Torres.

Guest cast: Chris O'Donnell as Dr. Finn Dandridge, Diahann Carroll as Jane Burke, Richard Roundtree as Donald Burke, Roxanne Hart as Dana Seabury, Peter Page as Benjamin O?Leary, Steven W. Bailey as Joe, Elizabeth Sampson as Ruth O?Leary and Javier Grajeda as Jeffrey Hernandez.

"I Am a Tree" was written by Krista Vernoff and directed by Jeff Melman.

Couple of things: Why would Addison need to take "a break" from Seattle Grace? Maybe, just maybe, she's torn up about the state of her marriage. Also, I think this is the first we're hearing of Queer as Folk's Peter Paige guesting in the episode. But I could be wrong about that.
