"..I see. Thank you very much for the explanation. I only have two more questions." "Aito" said. There's no doubt in my mind..Bernkastel doesn't work alone. This "double" of hers, is probably the real Bernkastel, and she's probably bluffing us. I'll find you out, Bernkastel. Time to press just a bit more..
"One, out of the six of us here today, are we the only ones to have been in this hotel room, from yesterday to right now? oh, and when you answer this, please answer it as a short yes or no answer. If we are the only ones to have been in this hotel room from yesterday to today, please say exactly:
"Yes, from yesterday to today we are the only ones to have been in this hotel room."
and if we aren't, please say exactly:
"No, from yesterday to today, we aren't the only ones to have been in this hotel room."
Please answer my question with exactly with those two phrases and nothing more added." "Aito" requested.
Now, she'll have to give me a clear answer with exactly those two phrases. If she says that we are the only ones who have been in the hotel room from yesterday to today, I'll request to see her camera footage out on the front door starting from when she hooked it up, which was probably yesterday, to today. "Aito" thought to himself.
If I see someone, I'll be able to call her out on this. Then I can demand an answer. This will be an easy shortcut to look at the footage and see if I can recognize or see the name of the potential "7th person". "Aito" said, thinking out his plan.
However, if she says "No, from yesterday to today, we aren't the only ones to have been in this hotel room." I can assume it was only one person: Her act-in double. So to recap how this works to my benefit, in Phrase B we 100% assume her double was the person there. In Phrase A, we can 150% assume her Double is Bernkastel. Either way, it's a confirmation from a direct answer. "Aito" thought to himself.
