James watched her go. He needed to tell his mother and Clint that Rebekah had been there and knew where they were staying. They needed to move but James wasn't sure where they could go that Rebekah couldn't track them to. Short of completely leaving the area at least. But like Natasha had said, this was the last area his father knew they were at.
Once she was gone he leapt up onto the branches of a tree using his natural born enhancements (having two biologically/genetically engineered parents had it's perks) and moved quickly but carefully down to the cabin, wondering what they would do.
