"I'm--" Chloe paused when the woman looked up, her green skin was definitely startling but considering her best friend was an alien and she was a meteor freak, she had seen enough weird things to pull herself together just a second later. "I'm okay, I'm really sorry. I wasn't paying attention where I was going and I just tripped on you. Did I hurt you?"
There was definitely genuine concern in her voice and even though she was curious as to why the woman's skin was green, between the way she was dressed -- cover up head to tow, plus the long hair hanging as much over her face as possible -- was enough to let Chloe know that whatever the cause, the woman was uncomfortable with her looks and she didn't want to make her even more self-conscious.
