Well that's definitely a noise.

"Yes."

"Okay. I eat, you eat. Then I sleep."

So he finishes his food.

So does she, and then she pops back to Stiles' house to get her blanket.

"Hello. Nice to see you again. Happy to see you. Good. To see you."

Her blanket has been left untouched. 

"Hello. I stay Derek today, okay?"

"Derek Hale?"

"You probably don't know his last name. Alright. Sleep well."

And she nods and grabs her blanket and goes back to Derek's house, where she looks for a comfy piece of furniture to curl up on.

That night, no scream disturbs her.

And when the sun starts to rise, she goes to her cave to cook; she returns after an hour or so with a baked squash and two small bowls of oatmeal.

"Thank you. No victim, no murderer?"

She nods.

Derek eats his breakfast.

"I no understand why not. Kobld understand feeling, emotion?"

"No."

"This is happy. I want and I want to want and I have what I want. Understand? You can see I am happy."

She nods, somewhat hesitantly.

"I am sad. I do not have what I want or I do not want to want it. Sad is painful. You can see I am sad. My face is a sad face."

If 'face' doesn't seem to be clear, he makes sure to point his out. 

This nod is much less hesitant.

"I am angry. I want and you no want, or you want and I no want, is bad and we no have what we want. Anger is no I want kill you, is I want you understand I want kill you." 

Nod nod.

"Happy, sad, angry. Happiness, sadness, anger are emotions. I am happy, sad, angry. If I no understand, I am confused. See confused face."

Nod. "Is word - you are angry, I want go, I this?"

"If I think you are hungry and you are hungry, I understand you are hungry. If I think you are hungry and you are not hungry, I no understand." 

"...I understand 'understand', I understand 'confused'. I ask new word."

"New word...scared? If I think you will kill me or I no have food and I am starving,  I am scared. I want go and cannot go."
