I looked through a reprint of the very first Daredevil issue, and Foggy was in the audience with Matt during Jack Murdock's final fight. It also had Foggy and Matt going right from college into their own law practice, but let's ignore that part.
This "dude-vorce" is a big deal, as Matt and Foggy are practically brothers. If there is another DD movie or an animated series, Foggy's family should take Matt in when his father dies. Matt and Foggy going from friends to foster brothers makes their relationship even deeper.
Has the Kingpin ever done anything to Foggy? I know the Kingpin sent Elektra after Foggy in DD #181, but Foggy doesn't know that. IIRC, Elektra showed up and then let Foggy go, with her big Bullseye fight right after that.
