Well, he said no one at the agency knew but his boss Gibbs knew. Gibbs had only found out because of an event just like this during their second year of working together back in "03. Gibbs had shown up in the middle of the night, no phone call warning, and his husband had answered the pounding at the door. Definitely confused Gibbs when a man with black hair and green eyes opened the door in a night robe asking why someone was waking them in the middle of the night. If their house wasn’t layered in wards, renewed by Tony and his husband yearly, protecting them from any malicious visitors, then they wouldn’t have answered the door.
