I'm sure her roaring had complex telepathic strategizing behind it - but why did she keep her hospital gown on for it? Is she evolving into a prude?

The narrative or plot point leading me to believe the Abigail's are evolving back into humans? The WP show pic, at least on Hulu, is of what appears to be a human baby hand holding an Abbie's hand. All season I've been waiting for that to finally come up but the final few seconds is as close as it got.

The entire human race wiped out by a swipe left. Might seem a big dramatic sequence for another character but not CJ.

It didn't appear that Kerry allowed for the 13 hour incubation period. Does that cancel out the whole plan anyway?

Didn't Kerry leave the door to the mountain unlocked and the gate open?
