Merry stopped herself from saying but he didn't know then, since, even after he did find out Kenzie was a ghost capable of possessing people, he was still being a jerk about it. So she said, "Yeah," instead. "Listen, I'm not trying to fuck with you. I have nothing to gain by fucking with you. So, if you can, I hope you'll believe me when I say that I think Kenzie actually possessed you. I think she's a ghost, I think she'd dangerously obsessed with Joss, and I don't think it matters who gets hurt in her way. And I'm seriously not trying to fuck with you, this is what I honestly believe."
