When I didn't know that the trait wasn't needed*, I bought Johnny the "always welcome trait" and had him mooch in the Landgraab mansion. In this save I decided he was a distant cousin of Malcolm's on Geoffry's side of the family tree, disowned for failing school and becoming a comedian, just like the game suggests. Later he grew out of this behaviour, had a very succesful comedian career and also went into politics for some time (using the club system). When he found a wife, Johnny took her last name to signal his independance from the Landgraab.
*Note: Nowadays the trait would be needed for this, but that was back when there was only the basegame
In my main save Johnny was Malcolm's older brother who left the family because he didn't want to be involved in their crimes. He married Amber Stein, but both of them died when they helped a victim of the Landgraab during a kidnapping. The Landgraab got custody of Johnny's daughter and try to raise her in their own image.
Although I defined these relationships in my head canon, I never actually edited them in.
