She notices a small, black mark on the back of Delta's neck. She'd never seen it before because of all her hair
Out of curiosity she touched it
"GAHHHH!"
Delta jolts awake, screaming
She screamed with her scared then caught her senses back feeling confused but also concerned
"AAHHHHH!..What happened!? What's Wrong!?"
"Nnn...ah-owwww..."
She rubs the back of her neck, wincing. I should mention that Rein felt a dark aura from the mark
"..What is on the back of your neck."
"H-hm...?"
"Look at me and tell me the truth. What is on the back of your neck?"
"I-it's...nothing."
She's not making direct eye contact with Rein
"I said the truth Delta, what is on the back of your neck."
