Vida sat by the chair next to the bathtub where she was closest to Rudy's head.
"Since Kaguya didn't explain the process to you, we will have to do it this way. First, forget everything. Stop thinking and focus on my voice only. You don't have to speak if you think it will distract you, but let's set a signal for yes and no. What is the easiest thing you can do while in this state?"
Vida waited for a few seconds for a reply, but after meeting with nothing but silence, Kaguya said, "Didn't you just ask him to not speak if it's distracting?"
Vida shot a glare at Kaguya, but nodded soon after and uttered, "Okay, how about this. You don't have to do anything if the answer is yes. If the answer is a no, then move your finger in the bathtub, or do something that would cause ripples in the water."
Vida got up from the chair and signaled Kaguya to come closer with her eyes.
