Embora nunca mais seja mencionado na série de TV ou nos filmes, o vírus eletrônico conhecido como o Filhote faz uma breve aparição no romance da Trek " Jornada nas Estrelas: Espaço Profundo Nove: Valhalla " quando O'Brien a lança em para distrair uma entidade eletrônica conhecida como Enak que assumiu o controle da estação ...
Instructions were being countermanded. Signals were being blocked. New software subroutines were interfering with Enak's orders.
Enak was losing control. The Pup was out of its doghouse and in Enak's virtual lap, and it had noticed that Enak was running the station. It wanted attention, wanted to play, so it was doing the cybernetic equivalent of jumping up and licking Enak's face.
Distracted, countered by one of its own distant relatives, Enak was unable to dominate the computer systems; it was kept busy just dealing with the Pup's friendly overtures.
No final do livro, O'Brien retorna (aparentemente de bom grado) à sua 'casa de cachorro' virtual.
