In Plain Sight, Season 5

Dr. Shelley Finkel:
The pregnancy was unplanned?

Mary:
Uh, yes. Not that it's any of your business. I'm sorry, what does my family planning have to do with the shooting?

Shelley:
I don't know, but 39-year-olds don't tend to have accidents with birth control.

Mary:
Yeah, they do; all the time.

Shelley:
You want my theory? Your sister was getting her act together.

Mary:
Was being the operative word.

Shelley:
Your mother was sober.

Mary:
Still is.

Shelley:
You need someone new to protect, so you got yourself knocked up. So, my theory: what do you think?

Mary:
I think that the hour is up.
