Lucas is eager to spend an evening after work with Brahms, but doesn't want the senior staff knowing. To achieve this, he writes a secret love note addressing her as "Sexy Knickers". However, the note causes misunderstandings when it is accidentally dropped near Peacock, who hands it over to Slocombe assuming she dropped it, whereupon she reads it and assumes Peacock wants to date her.
