The ClusterClient is using forward so the original sender is passed on to the ClusterReceptionist, which creates a "response tunnel" actor. Your WorkerFSM should see that response tunnel as sender. It has the same name as the client actor, but is a child of the ClusterReceptionist. When you reply to that sender the message will be routed back to that response tunnel, and then back to the client. The reason for this is to avoid inbound connections from other cluster nodes to the client.
