And, honestly, Al and Courtney is rather different than it looked like Courtney and Billy were - he's only in his 20s, and by the time it was serious, she was 18 or 19.
Whereas Cap looks like he's in his 30s, and Courtney was only 16/17 at the time.
Al's not doing anything he could go to jail for. Neither was Billy, of course, but it LOOKED like he was.
