If it hadn't been for Russell's sudden stroke of inspiration, as if he had rolled a successful dice in a game of Spiritual Perception, when he asked for the identity of these attackers from No. 44 and demanded the hotel rescue Lemon-7 and Ethanol-5... he would still be unaware of the secrets involved.
He would truly believe that Naraku-7, through some means, had learned of the company's plans to make a move on them and decided to crash the airship they were aboard into the sea.
For all the intelligence prior pointed to this possibility.
However, now Russell had learned from Lemon-7 and Ethanol-5 another very important piece of information:
The missiles that brought down that airship were most likely not launched from the Heavy Mechanical Weapon controlled by the Synthetic Humans. And even the enemy Tartaros recognized this information... Even if it was still not the complete truth, it was at least very close to it.
