- You're not gonna turn her loose?

- Certainly not. Get her.

- Is there a phone near here?

- Next door to here.

- Thanks.

- Not bad. I have no complaint about the way you handled the problems of the lovelorn. Very tactful.

- White speaking. Yes, Jimmy. They took Lois with them? Stand by, I'll have Kent join you.

- Where are you going?
