Just wanted to place this brief discussion about Ghost and Null (as it is relevant to @CaptainSteve original topic) I stumbled on from the Storyline thread, which remains an interesting point, arguably because of the current ‘whodunnit?’ unfolding about the Virus. there are few additional comments in the storyline thread too. Perhaps the comments about Null should all should be moved here.

Since the posts were written, we now have more information about Ghost from the @the_architect response to the Operator questions of course.
@Polyphemus also made some interesting observations about Null too in response to the storyline thread.
