Helena was greatly relieved not only to have found Claudia but that she was well. She shook his hand. "Hello, Mike. I'm glad to hear about Claudia. We've all been extremely worried about her. Her counterpart, as you call it, wasn't very helpful in determining where Claudia had disappeared."

As for her own counterpart, Helena wouldn't know if she even existed. Over a century had passed since she'd been born. "Well, let me see: I'm employed by the Secret Service in the same area as Claudia. My middle name is Georgia. I've was born in London and relocated to America in 2010. Does that give you any assistance?"
