A young orphaned undercover detective on suspension learns from an FBI agent that his biological father’s is their current target.

How is his suspension causally germane to his being assigned to the new case? And if he's assigned because he knows the suspect, what happened to the discovery that it's his father?

He's not sidelined. The story begins with him being approached by the agent while on suspension. He's not with the FBI initially but is pulled in because of his relationship with their target.

I agree. Bring the detective in on the action. If he's your "hero", why have him sidelined?

The father is a criminal worthy of prosecution. The son after informed of the news must decide if he wants to help take his own father down or after getting to know him (under cover) tip him off and possibly suffer some consequences. Morale dilemma indeed.
