So, I looked at the guide and found that I am supposed to get the knight badge from the encounter with Asmund. It's been a while and I can't remember whether or not I won that battle, but I didn't get the knight badge or the lion key for that and now I can't revisit the encounter to try and get the items. What should I do?

Note: I did do this fight around when it first came out before you could upgrade your sword or use holy fist against him. Not sure if that's important info.
