There were only a couple of people Arthur trusted to take care of things for him and one of those people were in that flat with him. He listened to Eames' side of the conversation and felt his mouth tug up into an amused smile. He knew the difference between Eames' actual flirty voice and a front. At least by now he did.

Arthur took the phone from him, texted the coordinates to the apartment then pulled the card from the phone. He chuckled with a small groan before giving the forger a look. He appreciated the humor though, the urge to make him laugh. "No promises," he said with a wry look before picking up the bottle, opening it and taking a drink. "Your hands will be steadier than mine are right now, I assure you of that." He paused and looked at him. "I appreciate it, you know," he said, seriously.

After all this time, he didn't trust people easily. The only one, other than himself, that he gave any measure of trust to was Eames. It was why he allowed himself to be so open with him - in and out of the bedroom.
