Gwen looked at the girl who called out after her. Serena, was it? She looked like an innocent, naive girl who didn't understand how cruel the world could be. Nonetheless, Gwen couldn't will herself to hate a girl like that, she reminded her of who she used to be before everything in her life went downhill. She decided to stay, only because the girl asked her too. "Gwen." she answered simply. "I'm also eighteen. I guess, I have the power to manipulate light and heal things."

She didn't really use her powers that often, nor did she understand them. That Phil character, she assumed, was going to explain everything to them later. Either way, she was only going to stay a little while. She doubt anything he said would change her mind about saving the world and all that crap.
