Everybody likes surprises, right? Only if they're the good kind.
Good kind: Cooper arranges for a surprise gift to be delivered to Sam: A red-headed stripper named Ginger.
Bad kind: Cooper then has bad news to deliver to two young parents, Beth and Greg O'Brien. Their baby daughter Emily is suffering from Pelizaeus-Merzbacher Disease and only has five years to live.
But, that's not the surprise. After running blood tests, Addison discovers that neither Beth nor Greg are Emily's biological parents. Beth responds as one would expect a mom to react. She's horrified and confused. Greg, on the other hand, acts defensively as if he's being accused of a crime. Hmm, maybe he is?
[break]Since Emily was born at St. Ambrose, Addison and Naomi speak with their chief of staff, Charlotte King, who immediately gets her hackles up, too. There's only one other baby Emily could have been switched with, but Charlotte refuses to turn over any medical files without speaking to an attorney first. She's acting mighty odd, too.
Meanwhile, Sam checks in on one of his patients, Dave Walker, an alcoholic who lives with his mother Gloria and his teenage son Steve. Although Dave denies he has a drinking problem, he's been passing out frequently. Yet, when Sam currently examines Dave, he seems to be relatively healthy.
Then, Ginger the stripper has a bad rash on her butt, so she comes to see Pete at Oceanside for treatment. Not a bad job! And Addison, stop acting like you're not jealous.
[break]Another surprise: Charlotte the ice queen warms up. She hands over the medical files to Naomi. Emily was most likely switched at birth with Sarah, the daughter of Duncan and Melinda Stinson, who received fertility treatments from Naomi.
After calling the Stinsons in and taking blood samples, genetic testing proves that they are indeed Emily's biological parents.
So, somebody at St. Ambrose switched the babies, but Charlotte responds hostilely to the suggestion that it was somebody on her staff. For once, we're on her side. Where's the proof?
[break]Charlotte brings in a boat-load of files and papers, but there's no conclusive evidence that a nurse could have made the switch. Addison begins digging through the files to find an answer herself.
Duncan Stinson flips out when he finds out he has the wrong baby. He screams at Naomi, "You promised us a healthy baby!" He's sunk his entire life savings into fertility treatments and now he's demanding his money back.
Suddenly, Sam has another Walker patient on his hands. This time it's Steve who's deathly ill and blood tests reveal he’s been poisoned. But, who did it? Grandma?
Yep, Gloria is totally unrepentant. She accidentally got Steve sick while performing an old family cure for alcoholism. She doesn’t want to kill Dave with poison, she just wants him to stop drinking. What's Sam supposed to do? He has an obligation to tell Dave the truth, right?
[break]After hours of going through St. Ambrose's records, Addison finally solves her mystery. Visitor logs show that the only person who had time to switch the babies was... Duncan Stinson! Furious that he was going to get a sick baby after shelling out so much money, he switched his newborn for a healthy one. Addison calls the cops who haul the creep away.
Having solved his own mystery, Sam calls Dave to Oceanside. In front of Gloria, Sam tells Dave that he has developed a serious allergy to alcohol. What? If he keeps drinking, he'll die. Hmmm, we don’t agree with Sam about lying to a patient, but maybe it’ll get Dave the help he needs. And who wants to see Grandma going to jail, anyway?
But now it's time for the teary swapping of babies to their rightful mothers. Melinda and Beth are bawlingXXXXXand, quite frankly so are weXXXXXas they exchange parenting notes about Emily and Sarah while handing each other their proper baby. Our heart especially goes out to Melinda who is only just meeting her real daughter now and then must tragically lose her in five years to a terrible disease.
It's hard to fight back tears over that. It's so hard that even Charlotte gets choked up. Maybe she has a heart after all.
