It’s a holiday celebration on Arrow Season 4 Episode 9, titled “Dark Waters.” There’s a party at Oliver’s campaign headquarters where they are celebrating both Christmas and Hanukkah. It wouldn’t be Arrow if at least one villain didn’t attempt to spoil the party.

Could this attack be what lands one of Oliver’s loved ones in the grave shown in the Arrow Season 4 Episode 1 flashforward? We’ll have to watch to find out that answer, but BuddyTV did catch up with Stephen Amell on set in Vancouver while he was filming tonight’s episode.

While he didn’t admit knowing the identity of the person in the grave, Amell does have “suspicions” and wouldn’t discount the possibility that it could be Felicity. “They can kill off anyone,” said Amell.

Prior to the Arrow-Flash crossover, Oliver stood at the podium and made it clear to Damien Darhk that he’s not going to help the mystical man. In “Dark Waters,” Oliver will make a move against HIVE, though Diggle may not agree with his viewpoint.

Check out the video interview below where Amell discusses the grave scene, Oliver and Diggle’s disagreement over handling HIVE and how Oliver now trusts all the member of his team and that they can handle themselves.

Arrow airs Wednesdays at 8pm ET on the CW.
