Eh, I thought the pacing was natural - about 1/3rd lighthearted playfulness (note the bright daylight and vivid colour during this section), 1/3rd investigatory build-up (note the more muted tones and colours during this section), 1/3rd climactic confrontation. I understand the point about Asami, but I feel that was as much previous episodes' fault as this one - if you bring a character and do nothing with them for 3-4 eps, you might need to rush them on a bit down the line. And I dunno, most people at least suspected Sato's company was behind Amon's weapons. I don't see anything else surprising enough to call convenient, other than maybe Asami's reaction and the new weapon. Amon's always scheming ways to turn events to his advantage - it's reasonable to infer that as soon as Sato was alerted to the investigation he told the boss, and he came up with the plan to lure the crew in with a fake mole.
