Ah. There’s my answer. I shouldn’t have let the other player come into the scene. “You’re still really busy. This’ll be their conflict.” That would have made them lose the conflict (which of course I was pushing for!). The third character entering in and adding a die of dispo was the factor that tilted things in their favor. So, once a conflict has started, you can’t enter it. You ain’t in the scene. Good to know.
