Who's the father... Spoiler

of Leannes unborn child?

I watched the series but I don't remember them telling us who fathered Leannes unborn child. They said that would take a few days for the lab to tell them but if they told us, I don't remember. That would seem to be a huge part of the puzzle. Possible candidates are Matt, her current husband, her ex (she bought a one-way ticket to France) or a long shot, Gary.

Too many unresolved issues in the story.
