Why she in Season 1, never really formed a meaningful relationship, a romantic relationship with Matt, and why she then kind of just flirted with Foggy for five minutes and dropped it.
One of the things that I came into season three wanting to do, was to more fully flesh out the characters.
And so one of the things I wanted to do when I took over as the showrunner, was to more fully understand Karen and why she behaved the way she is.
And then why she had a chemistry with Frank Castle, but that never went anywhere.
