Felicity and Oliver in “Unfinished Business”

Felicity

You want to know why I didn't kill Diaz. I wanted to. I was ready to. But then I realized killing Diaz wasn't going to prove anything. The whole reason I wanted Diaz dead was to protect our family, and... what our family needs is a fresh start, one in the light just like you're doing. I want our children to know that they are the most important thing to us and that we would do anything... anything for them.

Oliver

You said "children".

Felicity

I'm pregnant.
