When Kisuke asked Askin, “Are you really hell-bent on preventing our escape?” Askin responded, “Are you seriously asking? We’re enemies.”
Then, at the end of the battle, Kisuke throws the same thing back at him in a different format: “Are you seriously asking? This is a war, of course I’m going to prepare.”
At the end of their fight, with Askin lying on the ground, he didn’t like that Kisuke had alluded, through his silence, to the fact that he already had a plan to escape Askin’s fortress. That silence essentially told Askin that Kisuke had already prepared for this outcome, meaning Kisuke had beaten him at his own game of absolutes.
Askin had told Kisuke with absolute certainty that no one could escape from his fortress, only for Kisuke to beat him in the very thing he had been absolute about, as Kisuke had already planned an escape route. The one outcome Askin had treated as an absolute was exactly the outcome Kisuke had already prepared to overcome.
So when Askin, lying defeated on the ground, spoke about the situation being “lethal,” it didn’t sit right with him. Askin had spoken with absolute certainty that no one would escape, yet he had been beaten in that very absolute. In Askin’s own eyes, he saw himself as having not earned the right to call this “lethal,” because calling something lethal would mean that the absolute he had established was truly fatal.
And that was precisely where Askin had failed, because Kisuke had already planned his escape.
