She and Parker (Her Ladyship's butler/chauffeur) are friendly rivals, of sorts; he invariably calls her Lil, as they spar back and forth in the Manor's kitchen.
Beneath that gruff exterior, it appears Parker harbors a genuine fondness for her. In The Cham-Cham, he fancies "taking cook out for a punt," on his afternoon off (perhaps the way to a man's heart truly is through his stomach!).
- In The Duchess Assignment, the Lilian puppet appears in two different cameo roles: at the Duchess of Royston's gambling table in the French Casino at the start of the episode, and again at the art gallery, admiring the Duchess' Braquasso painting, Portrait of a Gazelle. In Alias Mr. Hackenbacker, it was seen at the Café Atalante, Paris. In Thunderbirds Are Go (film), it played one of the reporters at the Press Conference.
