Ryan Mason was accused of murder when his friends, Patrick Quinn and Matt, disappeared due to an attack by a Camouflage Beast in an old house. Later on, he came to terms with this after being confronted by Connor and Jenny. (Episode 3.2) He is portrayed by Bertie Carvel.
When Ryan was a teenager, he and his friends, Matt and Patrick, broke into an old house for a laugh. While Matt and Patrick went upstairs, Ryan explored the rest of the house, when a Camouflage Beast came through an anomaly into the house, attacking Ryan's friends and then him. Ryan was able to escape by throwing ash from the fireplace in the Camo Beast's eyes, and then fleeing the house.
As Ryan left the house alive while Matt and Patrick disappeared without a trace, many accused Ryan of murder, when he was in fact innocent. Ryan attempted many times to return to the house to find out what really happened, but never drew up the courage.Fourteen years later, by which time Ryan had gotten a job at a fairground, Connor and Jenny tried to ask him about what had happened in the house, but Ryan was initially not interested. However, when Connor said that they did not believe what happened to his friends was his fault, Ryan explained to them what had happened in the house.
Later, Ryan finally managed to draw up the courage to go back into the house, where he, Abby and the team were attacked by the Camouflage Beast. Danny Quinn then arrives at the house and points a gun at Ryan's head, accusing him of killing the former's brother. However, the Camo Beast attacks Danny and knocks him out. Just then, the anomaly reopened and the Camo Beast went back through, but then returned and attacked the team. Danny then arrived and shot the Camo Beast back through the anomaly.
Shortly after, outside the house, Danny apologised to Ryan for accusing him of Patrick's murder, and the two made their peace. (Episode 3.2)
