Abby: I can't shut my brain off. I keep thinking, why is the dopa at 17 instead of 20 and why don't they change the tube position? I can't see his eyes. Do you know what color they are?
Luka: They're blue.
Luka is actually teasing Abby in this scene; she's forgotten that Euro-American infants are generally born with silver-blueish eyes that change to their permanent color at approximately six month of age.

This is the first time we see Kerry walking without her crutch.
At the drug-testing clinic, the nurse asks Dr. Clemente for a mid-stream sample. He promptly proceeds to give her a full-stream sample. Obviously, he would have known better, and she should have objected as well.

Goof: Luka states that identical twins run in his family, but in fact there is no hereditary trait that influences a predisposition to having identical twins. The causes of monozygotic twinning (when a single fertilized egg splits into two or more embryos) is not known; technically it's a malfunction of the normal development process. Although there may be a high incidence of identical twins in some families, it is due to chance. Having fraternal twins, on the other hand, can run in the family, but on the mother's side only, as dizygotic twinning is the result of inheriting a gene for hyperovulation, which increases the chance of two or more eggs being released and subsequently fertilized.
Title This episode's title comes from a conversation between Abby and Luka about whether or not to keep the baby. During the scene, Abby points out that she is 37-years old and declares "if not now, when?".
