CONSULTATION RECORDING N-02 20:37
Are you feeling better now, Gloria?
A bit. I'm sorry, it happened again...
That's alright. Are the flowers and fragrances here able to calm you down?
Yes...
Is "Nightmare" causing your panic?
I don't know.
Gloria, for this consultation, I'd like to chat with you. I'll need you to try not to let "Nightmare" come out. Can you do that?
I... I can try.
Good, I trust in you. If she's about to come out, you warn me as loudly as you can, okay?
Mm. Let's begin. Last consultation, you said you were awake while "Nightmare" came out. What did it feel like, during that time?
It felt like... like I was sitting in front of a big screen. The sounds, and pictures... were all really clear, but I wasn't able to do anything.
You did something to take back control of your body. Can you describe that?
I ran and ran, and there were all these threads pulling at me, sticky, and dark, and I was pulling those threads... [COUGH], [COUGH]!
Gloria, are you alright? You have a very bad cough there.
Could I have a cup of water, doctor?
Here.
Thank you.
Let's continue. Were you doing that because you don't like "Nightmare" occupying your body? So you'd like to get rid of her?
No, I just feel... helpless. Like if I don't do this, I'll lose something.
What do you think of "Nightmare"?
She's different from me. She does things I can't do. It scares me a little.
Do you consider the two of you independent from each other?
Probably.
Suppose, and this is only me supposing, that one day, out of the two of you, only you were left. How would you feel?
I don't know... [COUGH] Sorry, I need more water.
Relax, it's okay. Now, we're going to try a slightly different method for our chat.
I'm going to have you recall some quite deep memories. Don't worry, I promise it can't hurt you in any way.
Mm. Watch my three fingers carefully. One by one, I'll bend them down, and they'll sink slowly into the deepest parts of your mind.
Three.
Two.
One.
Are you Gloria?
Yes.
Gloria, can you recall when "Nightmare" first emerged?
I don't remember exactly when, just... that night, I had a bad dream.
A bad dream?
Mm, I dreamed there was a white wall, with very bright corridor lights, and lots of people, and a lot of blood... and then, she appeared.
So she first appeared in your dream?
Yes.
Was she doing anything?
I remember, I dreamed she... saved me.
She saved you? And did she do anything else?
Ah... [COUGH]! Water, I need...
Calm down, take me through slowly.
Here–agh! That's my hand!
Heh. Heheh.
"Nightmare"! But why wasn't there any sign?
Oh, Gloria clearly warned you, you just didn't notice. What did you think? My imitation of her's quite a good one, isn't it?
Requesting backup! "Nightmare"–
Hush, not loud. Now, do you think that really was a bad dream? And just which of us could be after the Originium?
The twinflower, the doublet... truth and lie. How are you supposed to tell them apart?
Alright, now listen to me. Hand over the Originium...
