Jason is Eve’s younger brother. Jason has spent a lot of time in jail, and upon his latest release he began to stalk Claire.
He, along with Dean, attempted to drain Claire's blood and blame it on the vampires but Shane dad Frank Collins intervened with their plan and saved her.
He was unaffected by his father’s death, though he showed up to the funeral. He broke into the Glass house, and was chased down the street by Michael Glass, whom he shot in the chest numerous times.
It has been speculated by some readers that Jason may have developed some feelings for Claire.
