When Nikki and Jack arrive in the forest, DS Ross addresses Jack as "Mr Hodges", which Jack corrects to "Hodgson, Jack". This is perhaps the source of the running joke in the later Deschanel/Boreanaz series "Bones" where T.J. Thyne's character Jack Hodgins (also the entomologist/all-round forensic genius) continually needs to correct people who want to call him "Hodgson", "Hodges" or "Hodgkins".
