When does Huck believe that the Widow Douglas would be proud of him after the adventure on the steamboat?

Huck controls his panic and he and Jim frantically start searching for the boat that belongs to the men. Finding it, they jump in, cast off, and float away. Some time later, they catch up with their raft and get back aboard. Seeing a watchman on a ferryboat, Huck creates a tale about his mom and pop and sister who are marooned on the wreck and convinces him to go "rescue" the family. Huck is sure that the Widow Douglas would be proud of him for getting the "rapscallions" rescued.
