Jake was the young child of Dina.
One day Jake and his mother were stuck in traffic on the M25 while they were on their way to pick Jake's father up from an airport, so Jake entertained himself with a toy monkey and a Brachiosaurus. The cause of the traffic jam was revealed to be a rogue Columbian Mammoth and other motorists fled but before Jame and Dina could do the same, the elephant stomped on their car, trapping Dina under the steering column and knocking her unconscious. Ed noticed them and offered to help but was killed by the mammoth, scaring Dina and Jake.
Eventually the Anomaly Research Centre team decided to approach the car despite the danger of the mammoth; Abby Maitland and Connor Temple took Jake away from the car to be safe, as Nick Cutter helped Dina lift the steering column off her leg. As Jake hid in a truck with Connor, he sounded the horn, unintentionally saving his mother's life from the mammoth and later helped trapped it in the back of the truck he was in, by closing the rear door. Eventually the ARC team reunited Jake with his mother down the road. (Episode 2.6)
