Kryger on the Seraphim got a message from Spark's daughter on the other ship… that was the picture… which he believes was cut short by ISEA…hence him stealing the footage that was part of the truncated message from the other ship.

Hmmm, space viruses which are sentient are aliens, right? It was only Sparks' daughter who decided it was a virus in order to explain the psychotic behavior of her astronaut colleagues. "They are already here," having caught a ride in Molly's womb. And "they" seem able to control the people around "them."

Why would Molly's embryo have the answer to replicating the healing goo which was found in a meteorite?

I read the book, and I haven't had the least desire to watch the show.
