"hope for the future"

I think Foggy knowing though does explain how quickly he reorients himself around Matt post reveal. Foggy has some serious concerns with Matt as DD, partially because he's terrified of finding his best friend dead in an alley somewhere, and partially because the show's nuanced take on vigilantism and the legal system does force us to acknowledge that even if he's saving people, a random dude running around in a costume may not be the most effective way to stop crime. Obviously, we as the audience know that Matt loves his community deeply, and the corrupt police force in Hell's Kitchen is unreliable. But It's a great way to show the nuance of the everyday people in a world as big as the MCU. But most notably here, Foggy doubts Matt yes, but that doubt is very brief. Once Foggy wraps his head around the knowledge of Matt as DD, he openly states that he's starting to believe in the good of DD, even lying to Karen and saying that DD has helped them in the fight against Fisk (Which he has, just not in the way that Karen thinks). But he also begins actively reworking his own misjudgments about Matt's capabilities. Foggy has always known that Matt was an independent, capable person. Part of the reason they are friends is because Foggy acknowledges and treats Matt with adult gloves, even if he admits to feeling sorry for the issues Matt's disability brings him, something that very clearly upsets Matt. But once Foggy himself is aware of how capable Matt's hyper senses are, we see briefly that he begins to rework their dynamic. Even during the talk at Fogwell's, Foggy asks something like "Could you see that?" and simply takes Matt's word at the fact that he could. I think it reflects a lot of their relationship, Foggy not treating Matt as incapable, but simply asking casually what is and isn't the way to do something. It's surprisingly candid and I think that straightforward sort of no-nonsense casual approach is what won Matt over in the end. The realization that Foggy response to DD wasn't to view Matt as incapable, but rather to rework their system around Matt just like he's done their entire friendship, except this time the truth is fully out in the open. I think that detail, that Foggy knew about the boxing, does a lot of lifting as to how quickly he comes around once both have had time to cool. Matt's boxing history and Fogwell's aren't as big of a secret as Daredevil, but it's clearly something Matt holds close to his chest. Both due to being aware of how other people treat him and his blindness, and also because of the emotional weight it carries due to his father. I think that moment says a lot about the way Matt and Foggy function in their relationship. They aren't perfect people. Matt is traumatized and prone to guilt and being reckless. Foggy is shown to be deeply insecure, still too trusting of the system, and in some ways hesitant to run full speed into things
