Food for thought people:
My lovely imagination has come up with this hypothesis (I mentioned I had some thoughts running through my head in the comments of HFQ Snippet #1) well here it is:
Sejin Kody was a PICA (too much evidence points to that) now who out of Shan Wei's group had a PICA? We know only one was packed but we all assumed it was activated only when "Merlin" woke up at the beginning of OAR.
Who said Kau-Yung Pei or a close ally or another of Shan Wei's hidden operatives didn't activate Nimue to trial the 'hacked' software to ensure that 'she' could be active greater than the 10 day cycle so that she could do the true mission of Operation Ark. Afterall it would be no good if the hack did not work.
After trialling the effectiveness of the hack he or someone else on his team shut Nimue down and wiped the memory.
Anyway just some food for thought
