So in the comics, Matt has struggled with depression, and I think you can see elements of that in the show. Karen's mental health in the show is going through a rough patch too ofc, especially after the shooting and Ben.

I'd like to see them awkwardly (and maybe on Matt's part with a little reluctance) trying their hardest to deal with it together, because as much as they both love Foggy there's stuff you only reallly "get" when you go through it.

Bonus if Karen knows or learns about Daredevil.
