For instance, everyone now understands the meaning behind Finn Lewis's recent words and what has been disclosed through certain television stations; if the content of this video is true, it implies that these adversaries are humanity's greatest enemy.
There is no doubt about this; no one would deny it. Under such circumstances, they also understand that unless united, humans wouldn't stand a chance. In fact, even with a united front, it's uncertain whether they could defeat the enemy.
At the very least, they currently have one advantage: the enemy hasn't secured their footing in the Heritage System. This gives them plenty of opportunities. However, without the enemy present, they can't discern whether Finn's words are true or false.
