Doc Martin, Series 2

(Last night, while drunk, Martin Ellingham told Louisa Glasson that he loved her - and then he passed out)

Dr. Martin Ellingham:
-I embarrassed myself.

Louisa Glasson:
-No you didn't embarrass yourself. And I'm really glad that you said what you said. I just wish I'd had chance to say that I do too. I love you too.

(Martin stares at her)

Louisa Glasson:
-What?

Dr. Martin Ellingham:
-Love is...

Louisa Glasson:
-What?

Dr. Martin Ellingham:
-It's a difficult word when you think that we don't actually know each other that well.

Louisa Glasson:
-Martin, we've known each other quite a while now.

Dr. Martin Ellingham:
-Strictly speaking, for you to say you love me when you can't possibly know that you do is... potentially... delusional.

Louisa Glasson:
-Oh!

Dr. Martin Ellingham:
-There are certain quite well-known disorders where a person falls, without good reason, for someone else and believes that they love them.

Louisa Glasson:
-(Gobsmacked) Pardon?

Dr. Martin Ellingham:
-De Clerambault's Syndrome, for instance. Also known as erotomania. More common in women. They fall for a man of higher social standing.

(The camera starts to track back to an aerial shot of the bay)

Louisa Glasson:
-Martin! What the hell are you talking about?

Dr. Martin Ellingham:
-Delusional romantic attachments. Often associated with an excessive intrusiveness into the life of the object of the irrational affection. Stalking, if you like.

(Louisa slaps Martin's face. The credits roll)
