Oliver and Lois in “Unfinished Business”

Oliver

Ever since my parents died, I've jumped around from city to city, from continent to continent and in all those years, not once have I regretted leaving anyone. But then I met you.

Lois

Then stay.

Oliver

I can't. Because there are more important things in this world than what I want.... and what I love. Someday I can explain why.

Lois

Don't expect me to be waiting around for that when you get back.

Oliver

I'm not coming back, Lois. At least not any time soon. I'm sorry. I never wanted to hurt you.

Lois

Well, you finally got around to it anyway, didn't you?

Oliver

This is it, the moment, right? The moment that I'm gonna regret for the rest of my life, isn't it?

Lois

Yes.
