What happens in the last book of a series of unfortunate events?

Answer 1

Lots of stuff happened in The End. Let's see... Kit Snicket died, Count Olaf died, it was revealed that Beatrice was the Baudelaire orphan's mom, VFD stands for Volunter Fire Department, Kit had a baby (the father was Dewey Denoument) and when she died the Baudelaires became the guardians of it, the baby was a girl and they named her Beatrice, the Incredably Deadly Viper reappeared and then had to leave again, the sugar bowl remains a mystery, the triplets never show up (some people think they're dead, based on Kit's description)...I can't think of anything else.

And in the very end of the book, the Baudelaires (after living alone on the island for a year) decide to head back to the mainland with Little Beatrice. Their ship wrecks on the way back (the shipwreck poster in The Beatrice Letters is of that shipwreck) and Little Beatrice and the Baudelaires are separated. I'm pretty sure that Little Beatrice hired Lemony Snicket to find the Baudelaires, Snicket tried to track them down by gathering information from all the places they'd been since their parent's deaths and he based A Series of Unfortunate Events on the observations he made (that explains why so much time has passed between when the Baudelaires were at a certain place, and when Snicket came there to investigate).
