Booker tries out every new drug and goes through periods of addiction. When something new (make up something fun) hits the market he dives right in. Either he's in an established relationship with Nile or she's just concerned as a friend. She basically can't change his mind about the drugs but she can at least be around sober and look out for him. This can lead to anything from soothing him though a bad trip to a smut setup.
