The final moments of the Season 3 finale of Revenge, fans were treated to one of the most shocking reveals in the history of the show: David Clarke (James Tupper) is alive! Not only is the thought-to-be-dead dude alive, but he’s a murdering machine, offing Conrad Grayson right off the bat. How did the Powers That Be make the decision to bring this character back to the land of the living? Read on to find out!

"It's hard to introduce new characters who don't have a past history with Emily, but will make her invest as much in their character," co-executive producer Aaron Harberts said at the ATX Television Festival on Friday, via TVGuide.com. "As we looked back, David seemed like someone who would shake an unshakable character to the core. She's certainly not predictable, but she's a machine and we know how she's going to react in certain situations, but we don't know how she's going to take it when she finally sees her father. What if he says, 'I'm disappointed in you.' And what happens when he crosses into Victoria's story and says, 'She did some things to you. You don't really know why, but there might've been a reason.' [David] is a new barrier to entry [and] he can fill in a lot of the gaps Emily wasn't privy to."

After three seasons of avenging her father, we can just assume that Emily Thorne (Emily VanCamp) will have some major adjusting when she finally sees dear ol’ dad again — especially since James will be back full-time in Season 4.

"We were thinking about David [returning], but out of the blue [James] actually texted me like, 'Don't you think it's time for David Clarke to come back?'” Harberts continued. “There are so many moving parts because he could've been [committed] to a series. We were on pins and needles because you start trying to convince the network of the story, but if he wasn't available it could've changed everything. When we pitched the last episode, that's when we went and made our deal with James to make sure he'd be around."

Isn’t it funny how things turn up? Well, considering the crazy things happening in the Hamptons on Revenge, we’re not shocked at all.
