Arthur didn't respond at first. His look sobered as he considered it and found that it was the truth of it. Eames probably did know more about him than anyone else did -- even Mallorie and his own parents. He nodded silently and rest his head on Eames' shoulder and closed his eyes some. "You do," he said out loud and his voice soft. He wasn't sure where they had crossed that line only that between the time they met and Morocco and even after Morocco, it had been crossed. Perhaps that's why they knew exactly which buttons to push to get a rise out of the other.

His lips curled up. Arthur wasn't used to asking for help but it was good to know, to be reminded that if he needed it, Eames would be there. "Same goes for me," he said, speaking both as a 'thank you' and an offer. He too was serious about it. If Eames needed him for anything, Arthur had his back. The man deserved that much.

"I am at that," Arthur smirked, sending him a wink in return.
