I remember what's happening to her because of his pod ass.
Duke always had an edge, just like Holly always had a past and Anna wasn't always the upstanding police chief, but this is all character assassination. He never would have shot anyone in the back, this is just bringing him down to Jason and Sonny's level (or now they're just building SuperMcDouche up rather than Sonny and Jason) just like Guza did to Robert and Holly in 2006 by bringing them back as a sniper-for-government-hire and a biological terrorist, respectively.
