Kassandra clapped happily when Kathy said she'd be teaching the both of them to communicate with each other. "Kathy, you are wonderful! Thank you from fingertip to fin!"

She watched them interact, Hiro laying his hand on Kathy's shoulder. She wondered if they were mates. Perhaps; if they weren't then Hiro was likely missing out. Kathy seemed very kind and intelligent. "I will be here, when it's time to learn." She unearthed the book from in between some kelp they had put in her tank, and started to read.

A day passed in peace. No testing, no people in white coats. Kassy read, swam around and ate unbothered, but she couldn't help feel nervous. It was too quiet, like the sea before a storm. 

"I wonder what is going to happen. Maybe they will decide to let me go? I will miss Hiro and Kathy."

It was almost midnight when the stranger showed up. Her steps were loud and striding, giving Kassy enough time to hide away her treasured book. She strode right up to the tank, looking down at Kassy with cold gray eyes. 

"Hello. I am Dr. Helena Price, Subject Ariel. My team tells me that you can speak. Go on, say something." 

Kassy swam backward, a little intimated by this woman. From her bearing, she must be someone used to giving orders and having them followed. She looked up at the woman but did not move, as one would do with a shark. You did not move until you were ready to swim for it, and she couldn't leave.

"Mm. Shy, are you? Let's see if we can summon up your speech." With a snap of her fingers, her tank was wheeled away.
