Out of the three who made it out of Midland Circle, Jessica was the one who felt Matt's loss the most. Not that the guys didn't feel it, too. It had been too close, it could have been any one of them down there now, but they hadn’t had enough time to get acquainted or at least initiate some sort of friendship with the guy, to banter and tease each other like she had, so when he didn’t make it out, she felt she had lost someone who could have become an important part of her life.
Losing someone in that absurd way, someone who put his life on the line for people who didn't even know it, whose loss couldn't be publicly mourned because very few people knew his identity, was something all of them could understand, though. His last wish was for the others to protect his city. So, in the end, he wasn't thinking about himself, but in the city he loves. An honorable thought.
After hearing the story from Luke's point of view, Claire figured the fact Matt chose to stay behind fit well to his martyr tendencies, though that didn't make it less sad or gave it more sense. As crazy as it sounded to her, she didn't feel as surprised or shocked by what had just happened as she initially thought she would. After zombies, ninjas and all the things she had witnessed before, having a building falling on a guy she knew to live a crazy dangerous double life ended up being basically... Well, just another day in the city.
His choice to stay behind devastated his friends. It had been unbearable to witness them looking at the open door, waiting for him to get in, the seconds passing and… nothing. They all offered their condolences, but still the whole thing felt so unreal and almost indecent to feel relieved to be alive, hug each other and even smile in relief, when two people were crying mere feet from them.
Later, Jessica reached out and offered her services to both Foggy and Karen, for whenever they needed help, “just call me and I'll break someone's arm or leg”. She said Matt wouldn't exactly approve, but his alter ego would. “Free of charge. I owe him”.
Karen took the opportunity to grill Jessica about what exactly had happened. She wanted to know every single detail that led Matt to stay behind never to be seen again. She hoped it would help her cope with what happened. She couldn't exactly agree with Matt's decisions, but using Jessica's skills wouldn't bring him back either. It wasn't for the lack of powerful vigilantes that the city wasn't protected. If she hadn't asked for or had the help of Daredevil himself, another vigilante wouldn't do. To her, it was as if she was replacing him. She only nodded and thanked Jessica for the offer, but never called her. Not for that reason, at least. A beer or two once in a while seemed like a good idea, though.
Aside from that, Karen felt furious and in denial, the stages often mixing. Anger for the injustice and sad for the loss of her friend and barely-something-else. Before they had the chance to fix what had been broken, he was gone. His broken promise made her try and understand for herself if he ever meant to keep it and had his hand forced back into action or he just said what he thought she wanted to hear. Either way, he couldn’t answer which one was right. She hoped he hadn’t regretted whatever choice he had made. What she couldn’t see herself feeling soon was acceptance. Something was telling her to keep her hopes up. She couldn’t understand or rationalize that, only feel it.
Foggy was torn between his grief and his guilt. He agreed with what Karen had said, that Matt wouldn't have listened to his requests to not go to Midland Circle, but still. The guilt often won the battle. His best friend now lay under a rubble of concrete and he facilitated that. Marci had said he couldn't have known Matt would choose to stay behind, that he wasn't responsible for his friend's choices, but Foggy hoped his grieving process would reach the acceptance stage before he drank all of Josie's inventory. Thankfully, working at Hogarth, Chao and Benowitz kept him as busy as he could have expected and it was exactly what he needed at the moment, so he couldn't concentrate on the thought that he needed to mourn healthily the loss of his friend.
