Whatever it is, time is ticking. The enemy is getting desperate. You suppose that, in the worst-case scenario, they'd try to fight to the death again. Or do something stupid that would force your partner to act in self-defense; which would solve the problem, but also upset him greatly.

>Speak to Hi-Commandramon. This is a chance to learn about the command structure of the city's military Digimon. Maybe you could convince him to cooperate, or see if there are alternate options they could discover.

>Go talk to Squid and hear out some options. There must be some kind of tech-related solution to this, that could end the fight without needing to execute literally every enemy involved.

>Write-in: Something else, some particularly specific solution you can think of, as long as it doesn't conflict with what you've established. You're not about to turn heel on the DOW, and Astamon isn't willing to just kill all of them while they're too weak to even pose a threat anymore.
