BioShock Infinite DLC adding new AI companion?

BioShock Infinite's first downloadable content expansion may add a new artificial intelligence (AI) companion character. A 2K Games developer has listed "DLC1" on his LinkedIn page (via Superannuation), with work including "animation and R&D for a new AI companion character."

No further details about this character were divulged and an Irrational Games representative was not immediately available to comment.

Elizabeth is the main AI character in BioShock Infinite. It is unclear how this new character, if it is added to the game, would affect Elizabeth's role in the game.

BioShock Infinite's $20 DLC season pass includes three expansions for the first-person shooter, said to provide "hours" of additional gameplay and include new stories, characters, abilities, and weapons.
