They didn’t say they kill him, here’s the actual quote:
“But before you connect the two, it seems the core four aren’t the only ones with major issues to contend with as season 2 continues. “What I can tell you is that there are some pretty big, explosive things coming for Archie, for sure,” Raphael Sbarge says. “It’s pretty dramatic — that’s what I’ll say. As far as where it goes from there, I believe the Once Upon a Time scripts and the nuclear launch codes are essentially kept in the same location.”
But one thing we won’t be seeing any time soon is the psychologist giving his take on Henry’s strange, fire-filled dreams. (Seems like a natural fit, don’t you think?) “I don’t have that on my radar yet,” he says “I agree with you that there’s an opportunity there, but we haven’t gotten there yet. With the curse sort of going sideways, I think there’s ample job security for Archie. Everyone’s falling apart!””
I do agree that if something happens to Archie is exactly like the town would lose its conscience – he would be therefore an obvious target for the villains? 👿
