A decent episode albeit a little predictable. Richie , Dunca's new friend wants to find his roots. He learns that his real mother is dead but that his real father might be alive.
Meanwhile a conman Joe Scanlon gets himself in trouble with his boss who then tries to blackmail into erasing a gambling loss. The man poses as Richie's father so he can steal Tessa's artifacts. As mentioned pretty predicable however we do learn more about Duncan's own genealogy here and how he was outcasted by his own parents. There's a revelation there yet to be finalized so there was a parallel between Richie's problem and Duncan's past.
