User blog comment:D.Ryan/If Jack is Dead then why is'nt Bridgette Tenenbaum Dead yet?/@comment-1330314-20091109202128

Jack is still alive during the events of BioShock 2, if the player chose the happy ending to the first game. He just doesn't take a part in the story anymore.

On the other hand, Tenenbaum is still keeping an eye on Rapture, and so she will still feature in the sequel.
