Grey's Anatomy Season 9 Episode 12: "Walking on a Dream"

The ominous "ignorance is bliss" spiel is followed this Thursday (Jan. 24) by an episode called, "Walking on a Dream."

The official synopsis for the upcoming episode reads:

"The Seattle Grace doctors are on edge when a new medical professional enters the hospital; Arizona struggles with the emotional and physical pain of a phantom limb; and while battling pregnancy hormones, an overly-emotional Meredith is confronted with her worst fear."

Scroll down to play the sneak peek video at Grey's S9X12 episode. The preview opens to a joyful Meredith engaging Derek in a steamy moment. Then she cries. Expect a combination of comedy and drama from the central character of the series as she deals with the realities of pregnancy.

Meredith has officially come out about infanticipating. It is implied Meredith is hopeful that her harsh uterus could provide a home for her baby before due date. But of course this woman has deep-seated fears. How strong will she be in a battle against herself?

Meanwhile, Arizona is seen in the promo clip saying, "I'm going crazy." Perhaps the phantom limb will send her back a few steps. Fans will sympathize considering she has just made some progress with Callie. But the Calzona couple has been strong against many challenges in the past. This is just one of those dark phases that Arizona has to go through to establish her iron will and graceful heart.

The video shows nothing on the aftermath of the plane crash lawsuit. But viewers can expect the doctors to deal with the news. Seattle Grace Mercy West could close its doors as a result of paying off the crash victims. If Arizona had not gotten on the plane out of spite, the hospital's insurance company would cover the payments. How will Arizona handle this news? Ignorance is bliss. But it sometimes doesn't last.
