I like the idea of them meeting thanks to her teaching. Just imagine this grown man smiling and saying "Wait. Were you that teenage girl years ago who took on an entire gang of bullies to defend her friends? My father slipped up and told me the story- he was one of the cops on the case. I wanted to be like you when I got older."

Along with Matt's niece being a student at the school I was thinking that Matt sometimes shows up to the high school as the professional expert who helps with the mock trial club, so that might give them a chance to interact, especially if she ever fills in for whatever teacher looks after the club.
