Get him talking.

He's not going to tell me anything, and if he does, will I be able to tell if it's the truth? I'm not sure if my Kitty Sense can work from such a distance. He isn't actually right in front of me after all. Maybe I can get him to talk if I keep talking. He seems to like hearing his own voice. "When you say you have power and knowledge, you mean Breiah does, right?"

Vivi perks a brow.

After a pause, he speaks up again. "Never forget that I am the Demon King. She and I are partners. We simply have different skills."

"I don't know. When I was dragged to this world, it was her that I saw, not you. She was the one running tests on me. So it sounds like not only is she the brains, but she's the one who gets her hands dirty. Why aren't I speaking with Breiah instead of you?"

"Watch your tone," he speaks more deeply now. "Unless you want your friend to be exorcized."

Vivi steps beside you with her arms crossed.

Before she can speak, Elok talks again. "Ah... Her sister. Of course."

"She's listening right now, isn't she?" Vivi asks. Then she takes a deep breath. "Hey, sister! What do you think you're doing still helping this jerk?"

For a moment, he glances to the side, but then he returns his gaze to the mirror. "You are speaking with me."

You take a deep inhale through your nose, and sigh quietly in an attempt to calm your beating heart. Things aren't getting better, but it's delicate situation. You're not exactly sure what this cleric is capable of, nor do you know what other tricks Meti has in her disposal. The ants can be dangerous as well, even if they seem childish, and these ALICEs seem to be Elok's shock troopers, so having even one present is dangerous.

"If I said I wasn't planning on traversing the rest of the tunnel anyway, could we just leave now?" you ask.

"To be frank, Mr. Warren, we have long been enemies now. I tried to work alongside you before, but it has become ever more obvious that you would never join me. Therefore, it is in my best interest for you to fall. I am sad to say you are in a dangerous position right now. Your right-hand-girls are not present, and while your current company may be capable, I do not believe you will all escape this day. Goodbye then. I have many things to attend to at the moment."

Before you can respond, his reflection vanishes, and right after that, so does the mirror in a flash of light.

Like a tingle down your spine, a feeling through your body tells it to react before you can even consider it further.
