Adrian Kali Turner has been announced to be playing little Duane, who is one of - if not the first - living people that Rick encounters after waking up from a coma in AMC's The Walking Dead tv series.
Now that Duane has been announced, the role of his father, Morgan, is yet to be made official. Although Keith Allen Hayes was just cast in an 'unannounced' role a couple days ago. Could he be playing Morgan and not Tyreese? The character of Morgan may be more likely now, considering Tyreese isn't a presence in the comic until later on.
