The Wasp was taking too long, so if he didn't feel it worth his time then he can find someone else willing to pay him. Or perhaps he ratted them out to the vultures so he could get a closer look at the Titan, but seeing as the guards weren't keeping alert to some imminent attack he safely assumed they hadn't been found out.
"I don't know the specs of most of these Frames, seeing as the vultures aren't a uniform army they all use stolen or scrap frames. From what I can tell the patrols outside the walls aren't falling to pieces and the anti-aircraft frames on the towers are pretty stationary" Sean knew it was now or never, so he started the orders "Svyatogor and Anemoi, you are green to go. Keep it quiet and thin out as many as you can before being noticed. Ghost and Goujai, ready your fire for the AA Frames on those towers so that we can keep our fly boys airborne. Golem I want you close to me, you watch my back and I'll watch yours." He wasn't sure just how Jack was feeling about him now, seeing as his history as a bandit and Golem's history as a bandit killer don't create a friendly work environment
What Argile worried about most was when he wasn't Jack's employer anymore; would he be inclined to kill him just to follow through with his reputation? Or would he see that Jack is a changed man for the most part?
