Fringe, Season 4

Lincoln:
You're not returning these people to their families?

Olivia:
We can't do that.

Lincoln:
Why not?

Olivia:
Because we can't disclose how they were killed. The families are informed that they have gone missing and we will continue to look for them --

Lincoln:
You lie to them.

Olivia:
Look, I'm sorry, but --

Lincoln:
You understand what you're saying? Those families are going to spend the rest of their lives wondering what happened to their loved ones. Looking for answers. Can you imagine what that would be like? To have that -- that hole in your life.

Walter:
People die. It happens. Sometimes they even die twice.
