Jack backs away from the touch. He scrubs at his face again -- stop crying, jesus, get a hold of yourself.

He doesn't know how much Sinclair found out about him, and he's not sure how to ask -- but maybe it doesn't matter, it's got to be too much no matter what the amount.

"Fontaine said I could trust him," he mutters bitterly. And then it turned out Fontaine didn't even use his own voice or name to say it. A moment later Jack wonders why he's saying anything -- but why not, Sinclair's seen the photos and heard the diaries, it's not some big secret that Fontaine's one of the skeletons in Jack's closet. And whether or not Sinclair gets it, that sentence is kind of the foundation of why Jack probably shouldn't be trusting anyone any more, no matter how easily trust usually comes to him.
