Dr. Will Halstead and Dr. Natalie Manning in “Unfinished Business”

Dr. Will Halstead

I don't believe this. I... I miss something with one patient, and it's too late to fix it, then I catch something like this early on, and I still can't fix it. Nat, the medicine is clear. The patient should not be making this decision. I should.

Dr. Natalie Manning

So you became a doctor to tell people what to do?

Dr. Will Halstead

I became a doctor to save people's lives. It's all I've ever wanted to do. I don't have a fallback plan or some hidden passion. This is it for me. It's just... no one ever told me there'd be this much loss involved.
