The Walking Dead - The Walking Dead: Season 2 - Episode 2: A House Divided
And I'd say Carver is either 47 or 48.
Both men also look to be around the same height and weight.
The biggest difference between Kenny and Carver, is that Carver is brutal, vicious an ruthless.
Kenny, even though he has had to kill to survive, does express regret for the things he has done. And Kenny also expresses sympathy for others who have experienced loss.
Carver is psychotic.
He appears to be willing to kill anyone for any reason.
And he expresses no remorse for the people he has killed.
