Jack reaches Ryan's office, finds it empty, and goes cold.

He opens his mouth to call for Sinclair, but... he doesn't really need to. I mean technically Sinclair could have left by the door and gone somewhere else but no, what's far more likely is that he has decided to search that long corridor and jesus god they should never have come up here.

He's expended a fair amount of effort to keep the facts of his past a secret, and with good reason.

So he sprints up the corridor as if there are hounds snapping at his heels, and as the door opens he sees Sinclair -- bad -- and hears a tinny recorded voice speaking -- infinitely worse.

Jack does the first and fastest thing he can think of and yanks the audio diary straight out of Sinclair's hand, no preamble, no pause. And it won't stop talking and he's kind of panicking a bit, so with burning hand he straight up crushes it against the wall.

"What are you doing in here?" he demands, as scared as the kid in the recording when his dog's neck broke, and twice as angry. "Get out!"
