I won't comment on your use of Cardamine. Many Artificial Intelligence machinations stretch far beyond our own levels of intelligence, while some are simple, rudimentary programs with a singular goal or no goal to function from. Be that as it may, there are far worse things to fear.
As for Keeper Revenant, she has in fact returned due to the deteriorating situation in and around Liberty. The heightened level of Nomadic traffic has us out fighting frequently, to prevent this internal squabble from becoming an access point for infestation. It's quite interesting to see the situation play out. One admiral dead, another missing. The Navy less focused on the Security Force and more on a threat from another kind while the LSF continue to barricade themselves behind their minefield. It makes you wonder if they know something is coming, or if they're expecting the worst outcome of the recent conflicts. No matter. Our priority is to keep the infestation from spreading in to the House.
Funny how - once again - The Order is no where to be seen when fighting the Nomads and their thralls.
Lastly, your proposal seems to be more of a demand. Nevertheless, a level of neutrality can be offered. We all have bigger concerns occupying our time than to allow petty squabbles of the past and names of our friends to dictate where our focus should be.
