Uh huh.
He goes home. He reads some Asimov and some Pratchett and some Williams; he forgets what happens in each page after he finishes it. He vaguely tries to work. He talks to Serena without paying attention. He has sex with his mistress without paying attention. He plays with a pen.
Zaida is being abused. No one is going to do anything about it. She has a mom and an aunt, who apparently did a very good job of raising her.
He leans on a few people in CPS, calls in a few favors, makes a few promises, gets someone's kid an internship, gets someone's cousin let off with a warning. Everyone smiles and says "we'll get right on that, Commander Waterford" and never talks to him again. At church every weekend, Zaida is covered in bruises.
Melton is a high-ranking Eye, or he has blackmail material on someone important, or he's doing someone important a very big favor, but either way Fred can't touch him. He makes a list of the leverage he has and he thinks about the best way to use it.
He doesn't decide that he is going to kidnap this toddler. He withdraws some cash from the bank. Assigns Nick to provide support for Chris, whose wife had just had a baby. Packs up a suitcase and leaves it in the trunk. Makes sure his tank is full of gas. Tells his subordinates that he might disappear unexpectedly, hints around that it's Eye business. Keeps an eye on her and waits for her to run off again.
