Fecund
Tony's conduct had kept him alive during a time when gay relationships were frowned upon. The truth was, he wasn't gay. He was bisexual.
He slept with men and women. It was always casual, at first. He was just looking for some fun and maybe trying to get his father's attention.
Then he started to grow up. Some would say he still wasn't grown up, but the truth was that was just a mask he used. By the time he joined NCIS, Tony had a son.
He'd proven his fecund abilities, but no one knew. Well he thought no one knew. The truth was Gibbs had figured out a long time ago that if Tony cut work early for a date, it was actually something to do with his son.
It was rare that Tony needed to leave early, but Gibbs also knew that Tony made sure to spend plenty of time with his son. Tony preferred overnighters because it gave him an excuse to be home during normal working hours the next day and thus time to spend with his son without anyone knowing.
The only thing Gibbs hadn't figured out is why Tony thought he had to hide his son. For Tony though, that came from long years of working undercover where it wasn't safe for anyone to know about his son or he might be used against him.
