I’m not sure even The 100 would reveal that a key character is pregnant, only to brutally kill her off.
The death of one of the last two “Primes” might set the Faithful on fire, and Sheidheda still has control of them.
That said, The 100 seems to be dropping clues that Emori could be pregnant with Murphy’s child, not the least of which was Nikki’s comment that Emori had a “glow” to her.
Indra and Wonkru would side with Murphy in the event of Emori’s murder, and the result could be a good old-fashioned 100 bloodbath.
