Somehow, sifting through all the threads and connections of the Fisk fiasco, someone finds out that Karen was the one kidnapped by Wesley and subsequently his killer, and she gets called to trial to testify against Fisk's actions. She doesn't want to talk about it, she can't stand that everyone will know even though it's clear it's self-defense, and of course what if Fisk eventually finds out it was her? Show me what happens, how Matt and Foggy react to knowing that this is the secret she's been carrying around. Can be gen or romance or whatever!
