Warren had been out trying to find one of the two people who were causing all the commotion with a lot of the people in the complex. He hadn't told Kara he was going, but then he didn't even think he had to, she would have probably only told him not to go. He figured he could last against the vampire, especially if fire kills them like he was told, but instead he came across a girl in the park that seemed a little out of place, like she had just arrived in this world. She was carrying a sword and the cops were pointing guns at her because she was causing a scene.
He went over to the situation. He couldn't let her get arrested and say she was from some other world or time. They'd never be able to get her out fo the looney bin. Then if he ever mentioned his powers, they'd probably do the same to him. "Officers, She's not well. I'll get her home. I promise." Thowing her a look, trying to tell her he was only trying to help.He was, after all, a superhero back home. He wondered where she came from, but also remembered how confused he was when he first arrived.
