Might the following casting tidbit reveal the identity of Jack's Sideways world baby mama?

It's been confirmed that Michelle Rodriguez will reprise her role as Ana-Lucia in at least one of the show’s final episodes. The character was killed off in season two, of course, making it likely she'll appear in a parallel universe flash sideways.

Meanwhile, producers have said that the mother of Jack's son, David, is someone we've met before. Fans will be in an uproar if it's actually Ana-Lucia, but we're gonna wager against it. Our money is on Juliet.

Rodriguez joins a long list of Lost alums that will at least make a cameo this season. It includes Maggie Grace, Harold Perrineau, Cynthia Watros, and Rebecca Mader.
