Before Jeff had changed the world, Roxie had few concerns in the world. She had other dogs to play with, she had food. She didn't give much thought as the strange humans walked past her...partly because she didn't have much thought to give.
After Jeff activated the Chronovac, from Roxie's perspective, nothing was changing. Despite that, she had been getting more intelligent by the second. She didn't notice how she was suddenly clothed, or a few moments later, how she stood up on her hind legs, which were gradually growing longer.
Not only was she growing more intelligent, but she was gaining knowledge, and with it, her personality was growing more complex. She started to grow opinions, hopes, dreams, and goals...but as her increasingly bipedal form filled her clothing out more effectively, she moved to where the two humans were playing.
The male human was sitting, as if waiting for something, but the female was looking around, as if trying to find something. "What's wrong, girl?"
The female whirled around and looked up. "Maddy? What is it?" Roxie asked, wondering what had spooked the human. Maddy was an adorable little blonde human.
"Ro...xie.." The human said, a bit garbled, in between pants.
