The concerns John had were similar to those that Cameron harbored. While it seemed like the John she knew from their short conversation over the network she knew she could not be certain until she was in front of him. Until she could clock the mannerisms this John presented against the library she had of her John - those small things that separated him from the John she knew in the future and the ones she were certain would distinguish him from some other option. She had spent nearly all of her existence studying John Connor, she felt confident in her ability to know for certain once she could see him.
The decision to meet at the house seemed fair enough. She knew John well enough to know that was not where he would be staying. Even if this place was different it was still a compromised location, and she was content to see he didn't immediately trust her enough to lead her to his actual location. He was trained well.
The idea that John had chased her chip to the future weighed on her as she made her way to the house, or at least as much as something could weigh on the mind of an advanced cyborg. "It's the hail mary," future John had told her before she'd gone back. The if all else had failed approach. She had to wonder if it would have been too soon. Was he really, truly, ready for the future following her chip had thrust him into it? She supposed with them here now though they would never know.
Cameron was armed. Though she left the shotgun she had intended to take into the prison to rescue Sarah. She still had a gun tucked into the back of her pants, a knife in her boot. None of these she wielded as she walked up to the house though. No, once she caught sight of John in the window she went so far as to raise her hands so that he could see she was not holding a weapon as she finished her approach.
She opened the front door and walked into the living room and lowered her hands. She scanned the room, cataloging the similarities and the differences and then looked to John. The boy turned into a man far too soon who her life began and ended with.
"We would have to paint sooner here," she offered, remarking back to the day he had found her in the living room measuring the shift of the house.
