I finished the subquest "Bridge Ablaze" by defusing the bomb under the bridge, talking to Waidwen and taking his soul with me. After I left the location through the starting portal, the paladin girl in the "hub" area approached me and made a comment about "an ember clinging to my cloak", thus recognising that I have contacted Waidwen.
