A nurse named Tom calls them over to baby Jacob, whose acidosis is worse. "Who picked him up?" Raab asks. Silence. Tumbleweeds. "Lockhart, he's yours. Go examine your patient," Raab says. Abby explains that Cardiology confirmed that he has a narrowing of the aorta, meaning that blood can't get to the lower half of his body. "Why is that bad?" Raab prompts. "His legs...need blood," Abby duhs. "If you don't know, don't guess," crabs Raab. Hey, it sounded right to me. Abby scowls as Raab explains that it's a sign of acidosis. Basically, his plumbing's all fucked up, and he needs cardiac Drano. Abby says that surgery is backed up, but that they can take him in the next forty-eight hours. Raab snaps that Jacob can't wait any longer, so if the OR won't take him, the cath lab will. An affronted, admonished Abby explains to Jacob's nervous parents that the cath lab can open the blocked aorta with a stent. "Surgery will cure him?" Kyle twitters. "It should, yes," Dr. Raab says. Anyone want to make a wager? Nah, it's too easy. Vegas is giving 100-1 odds on Jake's survival -- nobody's taking that bet.

As everyone disperses, Abby squeaks in one more disgruntled facial expression, because apparently anyone who corrects her or disagrees with her is wrong and unfair. Raab crossly prods Abby to nickname the kid. "Jake. Sounds tough to me," says Abby. "Jacob to Jake. Very creative," snorts Raab. Abby flinches at her. She knows a dramatic foil when she sees one.

Virgie announces that there's a delivery in progress, so Raab sends the students off to observe it. Abby lingers. "What are you waiting for? Go, learn something," Raab waves her away. Then she shouts out instructions to Tom about Jake's care, and Abby stubbornly stays put, insisting that she can take care of Jake because he's her patient. A hidden, satisfied smile sneaks across Raab's face before she stiffens up and hands over Jake's chart. "Get CT surgery on the phone and tell them that your patient needs the OR right now. Not in forty-eight hours, not sometime today," Raab says. So apparently, Abby is going to display moxie.
