In episode 13 of "Grey's Anatomy," the Seattle Grace doctors will be visited once again by the physical adviser while Cristina tries to find a balance between saving a patient's life and respecting the wishes of a dying boy's family.

The Jan. 30 episode, called "Bad Blood," features Dr. Alana Cahill (guest star Constance Zimmer) once again observing the doctors and how the hospital operates in an effort to help Seattle Grace Mercy West avoid bankruptcy. In episode 12, she suggested to the staff that the hospital close its emergency room wing as a way to save money. The idea did not sit well with some doctors - specifically Derek Shepard and Owen Hunt- and viewers can only image what she will recommend in "Bad Blood."

ABC released sneak peak photos for the upcoming episode in which the doctors partake in a lesson on a new operating technique. In one image, an instructor is shown talking to the doctors and behind him is a screen displaying details on a "tension free hernia repair," hinting that the doctors will learn a new method called "the varner technique."

The network revealed in its description for "Bad Blood" that Shepard and April Kepner will "work around the clock to find a solution for the hospital," and Arizona Robbins will empathize with a teenage patient who faces "similar problems" to her own. Also in the upcoming episode, Cristina Yang struggles to respect the wishes of a family whose son, admitted to the hospital originally to be treated, is on the verge of dying.

A preview clip for "Bad Blood," said "the thin line between life and death, right and wrong, will be crossed." Yang is shown telling the doctors her patient is crashing and when she asked "where is the blood?" the patient's father responded with, "no, no blood." She then told her intern "we have to respect his wishes," referring to the patient. Her intern then asked, "even though he could die?"

Watch "Grey's Anatomy" every Thursday night on ABC at 9/8 p.m. Central.
