"Lets start by talking to a few people." The Doctor suggested. He wanted to make sure she stayed close to him. He knew he wouldn't forgive himself if anything happened to her.
Rose nodded. "Who first?" she asked. She didn't know anyone here. She wouldn't anyways, she was far out of her own time. She gently held the Doctor's hand.
"Just anybody," The Doctor replied. He was looking around and went up to go and talk to somebody. He made sure that Rose stayed close to him. He was rather alert and was looking around. What ever was going on should be from alien influence.
Rose knew it was alien influence as well... or a very clever group of humans. She stayed close to the Doctor, knowing full well they looked like a couple.
The Doctor spoke with the human, only to find they had no idea and were completely scared. The Doctor was trying to calm them down and said he would work it out. His eyes scanned around a bit. "Ok well seems we need to ask a few more people."
