[earlier, Lewis had told Laura than he would not be going to New Zealand with her because he was afraid that he would not have a job to come back to]
DI Robert Lewis : I'll still be here when you get back.
Dr. Laura Hobson : That's what I'm afraid of
DI Robert Lewis : I've got something for you. What do you think?
[he shows her a shirt, bearing a picture of a dodo, that he has bought for her new-born niece in New Zealand]
Dr. Laura Hobson : Thank you. It's perfect. The dodo?
DI Robert Lewis : Famous Oxford icon. And a bird that I can relate to.
Dr. Laura Hobson : Except you're not extinct.
DI Robert Lewis : Let's hope that's still the case when *I* get back. From New Zealand. Where I will have been with you. If that's OK. I think I've been a bit of a fool. Well, actually I've been a *lot* of a fool. I'm really sorry.
[tearfully she hugs him]
DI Robert Lewis : I'll make it up to you, I promise. And I won't forget.
Dr. Laura Hobson : Yeah you will. But I'll remind you.
