He hires Latino men to tend his acreage, iirc. When he was being sponsored by the handheld saw company, he would put on a Mexican accent and joke about them. This led to a story he told about how he once owned a riding lawn mower that broke down and he never fixed it.
Google tells me that no contact orders in plea deals are almost always to protect a victim of a crime. Rolling with the rumor, the State may be asking that April has no contact with the children due to the daughter who tested positive. This has the same effect as no contact with Nick assuming that he wants to keep his kids and April.
Unfortunately, that brings us back to where we started. No one is charged with a crime wrt the child who tested positive.
