Revenge's David Clarke is alive and well, a plot twist that will throw a wrench into the reasoning behind Emily Thorne's recent actions.

No New Love Interest For Emily On 'Revenge'? VanCamp Dishes On Aiden's Death

After three years in the Hamptons, David's (James Tupper) daughter final complete her quest for revenge and cleared her father's name while doing so. Although her enemies are (seemingly) vanquished, the return of an allegedly dead Mr. Clarke will throw Emily's (Emily VanCamp) past into a tailspin.

"It will be interesting to see how fans react to [the storyline]," said VanCamp, according to TV Guide Magazine. "Even though it could seem like Emily's revenge plan was all for nothing, Conrad and Victoria still ruined this woman's life. It's almost even more of an injustice that her father was alive the whole time."

What will happen when Emily discovers her father is actually still walking and talking? It seems like the revenge artist could chose to brood on her father's choice to leave her out of his post-prison life, or she could be forced to reevaluate if her actions were really worth the moral price. Either way, it sounds like Emily will have quite a bit of self-justification to contemplate during season 4.
