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 The Cham-Cham it played a guest at the Paradise Peaks Hotel. 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, and a guest at The Swinging Star.
