I love Kathreya and would love to see Kathreya in solitary confinement
 

...for perhaps five or so days. I'd love to see what she does without her cookie power. Aw, I just love Kat! She's so happy and cheerful all the time. But seeing her in solitary confinement for a long period of time would be very entertaining.

I think she'd be boring, she thrives off others and interaction. She'd probably just sit in silence, afterall - what else is there for her to do?

I think she would be boring and just talk to herself.
