This is something fans have been theorising since last season, so it’s satisfying to see this finally confirmed. But, in saying that, whenever we have flashback scenes, Reginald’s beard is usually a lighter brown colour, in comparison to the grey it is in later years. If this is a human skin that he takes on/off, does he have to “age” it somehow so he doesn’t blow his identity? And if so, HOW does that work???
