Not only does this place look too old and too dim for a reputable, upscale accounting firm, it also looks too dusty. It is like, this place has not been in use. This can't be Jie Ai's office building. Unless, Jie Ai really isn't an accountant and he really is not hired by any company?
"Dude, what is going on?" Jack asks as he tries to get a spider cobweb off his shoulder. Yeah, this place has clearly been abandoned. Jie Ai is not taking him here for a pleasant talk.
"Oh, nothing is going on, really. Just trying to get you off my back." Jie Ai's voice sounds a lot different than usual. It is quite emotionless.
"What are you talking about? What's wrong? Let's go outside. This place is too dusty," Jack then coughs on purpose.
"You had to be such a show off, breaking into that hostage situation in my neighborhood, and trying to be a hero, huh?"
