"Possible..." Dan replied. But he wasn't sure that was the case. Doors didn't seem to pull people through on their own and as far as he knew, natives to those door worlds, ones who hadn't been brought to the station, couldn't find the doors to come onto the station either. So that couldn't have been it. Dan was puzzled to say the least.
Dan watched as Zatanna tried her magic, his own expression inquisitive and confused. He raised an eyebrow, not entirely sure what she was trying. The words sounded strange, and not in the same way as hearing a particular foreign language for the first. "Hang on, were you talking backwards?" he asked. "What were you trying to do? Just there..." he asked. He was a journalist and by nature, curious. Full of questions.
