Considering her recent struggles with Frank Castle, I’m willing to bet that she had some serious comments to make about Matt’s life choices.
Karen is one of the only people that Matt willingly opened up to about his identity over the course of Daredevil’s two seasons on the air.
Even though it sounds like there will be a significant time jump, hope remains high the show will eventually give us a glimpse at how the scene played out.
Her relationship with Matt AND Daredevil runs deeper than arguably any other character on the series, so seeing her response to finding out that Mr. Murdock (who she thought was blind) was a superhero all this time could’ve made for a fascinating character moment.
