At this point, Arcturus had two thoughts running through his head: "You have got to be fucking kidding me!", and "Would this be considered an Essyrnian standoff or a game of chicken?"
Clearly, the situation had four possible resolutions: ALICE died, the archer died, they both died, or an outside force intervened. He liked the sound of that last one, but ensuring that meant preventing deaths and praying very hard for something to happen. Whether the bank heist succeeded or not was off the table completely, so for now, keeping people alive was the only goal. The demon only wanted him to be loyal to the anarchists, and Arctutus doubted that Chelsea would want him causing deaths. It would only break her naive views on what anarchism really meant. As there was no money to be found, the mission was a failure, and therefore he had no orders, and was free as long as he got back to HQ sometime soon. "For once, doing some good is in the realm of possibility".
"Look, Ms. Mordecai, it works both ways. However, I think that this brother of yours might be a tad more valuable than the guy I've barely talked to before today. You kill him, your brother dies. I kill your brother, ALICE dies. It's a no-win situation, but ultimately, the consequences on your side are much more severe." He hoped that was okay. "Make them believe you have the power", he thought to himself. "I am in power here".
