So we all know that Rebeca is pregnant. (And that she's a big jerk) When Clementine hides in the bathroom we can hear Rebeca say that that baby might not be Alvin's. Well whose else could it be? I personally think it might Carver's. In the "Next on the Walking Dead" it shows Carver opening the door and saying he's looking for Rebeca, which gives Rebeca a very worried look on her face. That's just a guess. What do you guys think?
