In season 3, we see Melba/Clarissa Mao on the war path to kill James Holden, willing to stop at nothing to achieve her goal.
However, in the last episode of season 3 she has a major change of heart, believing in him and helping to stop Ashford from trying to destroy the ring.
I may have somehow missed something, because this turn around seemed to come out of no where to me.
Why did Melba/Clarissa Mao decide to not kill Holden and instead choose to help him?
