Yeah, I always thought that resolving a Bond involved change. Not so much a checklist to fulfilled. If anything, that bond might resolve if the other character FAILED to stand by them. Or stood by them in a real hellish battle when they could have (should have?) run away. That's more like fulfilling a bond.
Most Bonds are a little more clear, like "... is soft, I will make him hard like me." One of my players fulfilled that after watching the target take a lot of punishment over two sessions, then play a crucial role in a nearly-overwhelming battle. The whole table was like, "yeah, that Bond is FULFILLED."
