When Picard and Lily are going through the ship and the part where Picard says the Borg won't attack if they don't see them as a threat, why is that? Why are other times the Borg are on their zombie hunt to assimilate, but in that scene they weren't? Why was that time different, and how did Picard know that? Wouldn't the Borg always want to assimilate? Why wouldn't they see un-assimilated beings as threats? Thanks.
