Bradley Simek was a teenager who was also a member of The Calling.
Left grief-stricken and unable to cope with his father's death, Bradley turned to the Internet for comfort and was subsequently recruited into the international terrorist group, the Calling which fed off his insecurities, loneliness as well as Bradley's need for companionship and also his anger against a world that he probably felt didn't understand him.
Bradley also sent regular emails to his father, none of them going unanswered due to the fact that Peter Simek was dead.
At some point, Bradley became a permanent member of the Calling.
NCIS Season 12Edit
In Troll (episode), Bradley was first seen leading NCIS Special Agents Leroy Jethro Gibbs and Eleanor Bishop to Curry, a basketball coach with Curry thanking Bradley before telling Bradley to go back to class.
In his first appearance, Bradley appeared to be quiet and unassuming.
However, in a later confrontation with Gibbs, Bradley appeared to be extremely aggressive and very loyal to the Calling, suggesting that his loyalty to the group was unbreakable given how he saw them as an important factor in his life although he displayed some shock upon learning that Ensign Janine Wilt was dead.
Bradley was a teenager, presumably sixteen years of age with short light brown hair that had a slight fringe at the top with the fringe covering the top of his forehead and green eyes.
As seen in various photographs and information collected during the investigation, Bradley greatly admired his father with the two sharing a strong relationship.
In addition to being injured by the blast, Gibbs was left stunned and shell-shocked by Bradley Simek's death with Gibbs presumably berating himself for failing to get through to Bradley.
This protectiveness as well as a resolve not to fail again would manifest itself in Gibbs's dealings with teenager Luke Harris and although Gibbs would attempt to save Harris from the clutches of the Calling, this would ultimately lead to disastrous consequences for Gibbs as he was later shot and left for dead by Luke in a street in Iraq.
