Duncan was one of Connor Temple's friends at the Central Metropolitan University, along with Tom. He had a wild imagination, and was obsessed with conspiracy theories. Following Tom's death, Duncan became obsessed with creature sightings and finding evidence of creature incursions.
At the University, Connor told Duncan and Tom about the Anomalies and the cover-up by the government, and how he had encountered a Gorgonopsid, but the two did not believe him. Duncan was convinced that Connor had gone mad, but Tom saw that Connor genuinely believed what he was saying, and the duo decided to prank Connor based on his belief in the Anomalies and the creatures.
The following night, while Connor and Abby Maitland were camping out in the New Forest investigating a possible new Anomaly incursion, Tom and Duncan sent an animatronic dinosaur into their camp to spook them. The prank worked, and Duncan and Tom then revealed themselves to the humiliated Connor, then fled the scene when the police arrived.
At the University's canteen, Tom and Duncan ran into Connor while he was researching Mosasaurs, and tried to gain an annoyed Connor's interest and reminded him that it was their DVD night, but Connor turned them and the DVD night down and left. Tom and Duncan discussed Connor's secret and how it had changed him, with Duncan suspecting that he was still upset over the dinosaur prank in the New Forest or had a girlfriend. Tom then decided that he and Duncan hatch a plan to learn more about Connor's secret life.
When Connor went to stay at Abby's flat, Tom and Duncan gave him a lift in their camper van, and also gave him a Roswell keyring that they'd hidden a tracker inside to learn what Connor's secret was. Duncan and Tom watched in shock as Abby kissed Connor, unaware that Connor had blackmailed her into doing it. As they waited in their van outside the flat for the Roswell tracker to indicate something happening, when Tom and Duncan spotted Stephen Hart going into Abby's flat, they believed he was Abby's real boyfriend and thus Connor was in trouble.
Shortly afterwards, when Connor, Stephen and Abby went with the team and the Special Forces to a football stadium, Tom and Duncan followed them in their van to outside the stadium's car park, and tried to spy the government activity from there and suspected that there was a secret government base hidden under the stadium. Later, when the Roswell tracker indicated Connor was coming and a Dodo which had swallowed the transmitter emerged from the stadium instead, Tom and a shocked Duncan captured the Dodo and took it back to their flat in their van; believing that the supposed government conspiracy Connor was part of was cloning Dodos, and the duo planned to get rich off exposing the alleged conspiracy by using the captured Dodo as proof.
When the Dodo began experiencing dynamic and aggressive behavioural changes and grew out of control, eventually, when it destroyed the TV and bit Tom, Duncan locked it in his bedroom. When Tom began to suffer from the Dodo bite, having been infected with the Parasite, and the Dodo threatened to break out of Duncan's room and wouldn't calm down, Duncan tried to flee the flat with Tom, but Tom went into a fit from the Parasite's influence and tried to attack Duncan; causing a horrified Duncan to flee without Tom and seek Connor out to get Tom help. Connor subsequently took Duncan with him and the team back to the flat in search of Tom, but they found Tom had gone and the Dodo had died of the Parasite. Connor and Duncan also learned from Nick Cutter that now that Tom's Parasite had matured, it was too late to save him from dying of it.
Later, Cutter and Stephen went to Connor and Duncan on where Tom could have fled from the team and what he would probably do, and Duncan resentfully declared that Tom would be trying to expose the supposed conspiracy, and also revealed how he and Tom had bugged Connor with Roswell. The team subsequently learned from this and the fact that the Roswell transmitter was in the dead Dodo that Tom would follow the tracker to Abby, and tracked Tom and Abby back to the football stadium in time to stop Tom infecting Abby with the Parasite. Duncan watched with the team as Connor went up to and reasoned with Connor, telling Tom that it was indeed a conspiracy and coercing and encouraging Tom into fighting the Parasite's influence. Tom subsequently fought an episode of the Parasite's influence off and died in Connor's arms as Duncan watched.
Between Episode 1.4 and 4.2Edit
Over the five years following Tom's death in the Dodo/Parasite incursion, Duncan became immersed in and obsessed with cryptid sightings and evidence and with finding evidence of other prehistoric creatures like the Dodos appearing in the present. Connor also severed contact with Duncan.
Connor finds that Duncan is running a website about sightings of creatures such as the Gorgonopsid and the Future Predator. Connor phones Duncan's mother to find out were he's living, and goes there. It is a seemingly delapadated appartment with the door to the building covered in coragated iron. When Conner knocks on the door Duncan is very suspicous of him, asking him for ID even though he knows Connor's face. He eventualy lets Connor in and tells him he remembers what Connor said to Tom just before he died, about a conspiracy about mind control which is what he thinks the creatures are about. Conner convinces him there is no conspiracy and Duncan shows him all the proof he has of the creatures. He then takes Connor to a construction site where homeless people, and for a while himself, lived, because there have been many bodies turning up and no one's doing anything about it because they're only homeless. While there, Connor finds a dead body and Duncan starts to get scared. Connor calls Abby to come and see the body to tell him whether it's a creature kill. However, when she gets there the builders start to turn up and Connor tries and fails to convince them to leave, when they torch one of the homeless shelters, it turns out the creature, a Kaprosuchus, is living there, which then runs amok. It chases Duncan, Connor and Abby but then Matt Anderson pulls up and gets everyone into the car. After the chase the Kaprosuchus ends up on a cargo ship. Duncan waits outside the boat, but when Becker stuns the Kaprosuchus and puts it in a shipping container it wakes up. While the container is in mid-air hanging from a crane, the beast jumps out. This scares Duncan and he runs onto the boat and into the maze of containers, the creature following. Connor chases after him, desperate to save his friend. Successfully hiding, they both survive, and Connor tells Duncan to inform him of any other creatures he hears about.
