And I'm guessing that Nick in his obtuse and ignorant way lawyerly argued that April didn't live there, wasn't accused of doing drugs, has no real care obligation so it was an unreasonable burden to require her to be clean or take drug tests. He's also not willing to give up the side piece.
So to protect his kids, they charged her with drugs. The state can now keep her away from the kids. Congrats, Nick, you talked them into charging April with a felony using half-wit lawyer logic because you won't protect your kids and they have to..
