Foggy ends up meeting the man who trained Matt as a boy, despite Matt's best efforts to keep that from happening (and also his best efforts to get Stick to leave the city and get out of his life). It explains a lot more than Foggy wants it to.

Hurt/Comfort, with Matt trying to protect Foggy, but Foggy ending up getting super protective of him. Also, Matt and Stick's super complicated and fucked up relationship.
