Hook, Line and Sinner

"We're doctors - we're trained to care for human beings and we're pretty sure we know what to look for. Cuts, infection, genetic mutation. As doctors we have an arsenal of weapons after any. Antibiotics to kill infections. Narcotics to fight pain. Scalpels and retractors to remove tumours and cancers - to eradicate the threat. But just the physical threat, for every other kind - you are on your own."

- Meredith Grey

 is the twentieth episode of the sixth season and the 122nd overall episode of Grey's Anatomy.

Quotes

 * Callie: I get it. You watch parents go through horrible, unimaginable pain every day. And you went through horrible, unimaginable pain when you lost your brother and your parents never got over it. But if we had a baby- our baby's not gonna be one of those kids in your NICU. Our baby won't be your brother. I mean, knock on wood, but- Do you know how happy our baby would be?
 * Arizona: I'm not broken. My lack of wanting to have a baby is not some pathology that you can pat yourself on the back for having diagnosed. I like my life, the way that it is. I thought I liked it with you in it. I hope I'm not wrong.
