Stromboli

Weightlifter, was the Strongman Night Traveller. After the end of the Night Travellers all that remained of the travellers were memories and films, it was from these films that Pearl and the Ghostmaker escaped. Pearl and the Ghostmaker robbed a film of the Night Travellers from Jonathon Penn's flat and travelled to the old cinema and played the tape releasing the remaining Night Travellers including the Weightlifter. Jack Harkness filmed them all and exposed the tape destroying them as they were just a film. Jack claimed that the Night Travellers could return if there are films of them out there.
