"Chloe," she introduced herself, smiling softly and relaxing when her obvious pause and staring didn't seem to offend the other woman. She had seen plenty of weird things in her life, but this woman seemed completely normal other than her skin color. And the color being green, she couldn't help but wonder if it was somehow kryptonite related. Besides, her name sounded kinda familiar. "Nice meeting you, I try to avoid tripping on people as a rule, but I don't always succeed." She said, to lighten up the conversation a little.
But since the woman herself mentioned her skin and it's color, and Chloe was already extremely curious, she didn't feel like she had to hold back from asking anymore, "your skin color changes?" Maybe it was more like a chameleon condition, since they were at a park. That could be useful.
