Anna gives birth to a child that is clearly different from the average baby. When she finally gets a chance to hold the baby after it was withheld by Siobhan and the others, she sees it has sharp black talons, and sharp teeth. However, when Siobhan disappears, so does the baby. The rapid fire exposition that dropped as many details about what was happening during the season clarified that Anna originally had twins, and the normal infant was killed in order to let the creature live.
