He runs into a slight problem

As James enters the house he notices that the girls are seemingly all waiting for him. To his surprise he continues to walk in to see if the girls do anything different.

As he gets to the middle of the room the door behind him closes and the girls slowly start to make a circle around him.

James begins to wonder what exactly was going down when a girl unknown to him steps forward. With a glazed look in her eye she begins to speak, "Sir James, welcome to our planet, Earth. We have been expecting you."

James quickly turned around and made eye contact with Samantha and gestured to her seemingly asking her if she knew about this. Samantha responded with a shrug, to which James took to mean that they were all in on it before he pulled up to their school.

"But, but, how did you know?" James stammers.
"Easy, she told us you would come." The girl in the middle of the room says to James as she points to a girl no more than 22 years old standing in the crowd.
"But how would you know that I was coming? We only recently decided that I would even be the one taking up this mission?" James confusingly responds.
The new girl steps forward and turns her back to James to reveal her long flowing brown hair her hair, which she then pulled aside to show the crest of the Erera. The girl then walked up to James and put her arms around him giving him a hug, and instantly James felt a warmth inside this girl.

"My name is Olivia and Ive been here living on this planet for 10 years now. Why don't you and I go to another room so we can speak in private."

James doesn't know what to think. How could this girl have been here all this time? Do the others back at the core know about her? What does this mean for his mission?
