Ned shows up to the racetracks with Lightning the following day, and he tells Lucius what happened.
Butch was using the arrest to force Miss Corrie into a sexual situation, and she, against her own wishes, submitted in an effort to save Lightning, Ned, and Boon. They're all released, but when Boon finds out how and why, he strikes Miss Corrie and attacks Butch, landing himself in jail again.
Hearing all of this, Lucius becomes angry that nobody stepped in to save Miss Corrie, and that she felt like this was the only thing she could do to save the boys.
Looks like Lucius is developing a strong moral conscience.
