I so very much hate those Buffy/NCIS crossover stories in which Gibbs is revealed as the biological father of one of the Scoobies (most often either Willow or Xander), takes their 'parents' to task for mistreating his kid (unless they've just been killed in something as mundane as a traffic accident), and then whisks said kid off to Washington to give them a better life.

Seriously?

Aside from, say, people like John Winchester, outright abusive parents or child molesters Leroy Jethro Gibbs is the last person I see as a good father.

He works how many hours a week when he's on a case? When is he ever supposed to be home? When would he have time to, I don't know, care about his kid's life, look over homework, join in during school projects, show interest in their friends and/or dates? He put the Marines first during his marriage to Shannon and his time as Kelly's father. And now? Now he puts NCIS over everything and expects everyone on his team to do the same. He is curt, impolite, domineering, emotionally walled-off, and unwilling to accept that anyone other than him has a right to an opinion, or, heaven forbid!, a different way of behaving or even looking at life. It's always Gibbs' way or the highway. He'd run off any potential dates who didn't meet his antiquated standards of 'polite, respectful and well-behaved'. Any child of his would grow up as an overprotected social pariah.

I wouldn't give a dog into his care, much less a kid.

Children are not miniature Marines, and cannot thrive when treated as such.

I'm so waiting for one of the aforementioned kind of stories in which the Scooby in question digs their heels in, insists on staying in Sunnydale, and goes to court in order to become an emancipated minor and keep control of their own life.

Because, you know, of course the Gibbs in one of the existing stories would never throw his own life into chaos and move to California in order to allow his kid to stay in a familiar environment after just losing their family. No, it's the kid who, on top of the grief and turmoil, is supposed to give up their friends, the school they're used to, and whatever stability they have left (aside from the fact that Sunnydale is no paradise) and move to a strange city in which they'll spend half a day at a new school, and the other half in an empty house... because their father's guaranteed to be out on a case on at least six nights a week. Swell.
