The CW's popular show "Arrow" is stirring up buzz with cliffhangers and hard-hitting action. And next week's all new episode entitled "Deathstroke" should be equally exciting. For spoilers from the show's executive producer Marc Guggenheim, read on.

Guggenheim recently sat down for an interview with TV Guide where he discussed next week's episode.

"The Sword of Damocles that's being held over her is a double edge sword - it's both physical and emotional. I can guarantee that by the end of Episode 18, one of those edges is going to cut her," the executive producer said.

Guggenheim also revealed some spoilers about what's to come for the character Slade.

"He's clearly not in his right mind. Episode 18 will give you a lot of insights into what's going on in his head. We really do get a much greater sense of Slade's agenda, where he's coming from, but also what's going on in his head," he said.

The executive producer also spoke to TV Guide about Thea. Apparently "Deathstroke" will focus on her character.

"Thea learns something pretty massive in Episode 18, and it will cause a tectonic shift in her relationship with Oliver," Guggenheim said."
