Something in her voice tells Sinclair that Tenenbaum wishes at least to some degree that Jack hadn't needed to come back. It was a good thing for several people that he did, but Jack himself is definitely not one of them.

But that answers that. Fontaine didn't die when everyone thought he did. Sinclair assumes he is now, though. It doesn't seem like Jack would be content to wander around Rapture knowing the man who made him what he is is still going about his business like nothing ever happened.

"It's a damn shame," Sinclair shakes his head, blowing smoke out of the corner of his mouth. "Almost makes you wish he never found out about any of it. All those years of memories, then to find out none of it ever happened. Poor kid."

That in itself is another feat altogether. Implanting memories of an entire lifetime up until where he is, a family, a home, experiences, a personality, hopes, fears, etc. And none of it is his own, none of it's real. The ultimate identity crisis.

But it's over for him now, Ryan's dead, Fontaine is dead, legitimately this time. He's starting over, rebuilding. And it's slow going, but Sinclair can already see where it's begun. And once they get to the surface, then he'll be able to make some actual progress. Things will get better for him, so at least there's that much.
