Under the Surface || Tony Dinozzo

After years of service in Naval Intelligence, Jamie Callahan joins NCIS as a quiet, sharp-eyed profiler with a haunted past and a steady presence. Still carrying the weight of his childhood in Dorchester and the responsibility of raising his younger sister, Jamie isn't looking for connection-just purpose. But as he integrates into Gibbs' team, his guarded nature and subtle strength begin to draw the attention of his new colleagues, especially Special Agent Tony DiNozzo.

Set in the early seasons of NCIS, "Under the Surface" is a slow-burn character-driven story about found family, trauma, resilience, and the quiet power of being seen. Jamie's presence challenges the team in unexpected ways, while his bond with Tony-rooted in sharp banter, emotional intimacy, and reluctant vulnerability-grows into something neither of them saw coming.
