Our Mutual Friend was the name of the boat, and it was the Dickens book that Desmond said would be the last thing he ever read while in the Hatch.

And Psy, the Purge was in '92, not '99, we're basically sure of. We know it occurred after February of '91 (Kelvin Inman was in the Army during the First Gulf War and was in the Swan, locked away, at the time of the Purge), and yeah, Horace said it was in '92. Even then, I don't think that Ethan was 15 yet. He looked more around 11-12, which would fit with it occurring in '88 or '89.
