As we're stood there I notice a middle-aged woman staring at us across the room. I'm trying to catch her gaze, but its kind of vacant. I guess she sees me looking and considers it to be an invitation. She floats over to us in this strange dazed way, and on the approach I realise she's staring at (through?) my Korean colleague / fresh meat. She's saying wow, wow, wow. She seems genuinely so delighted, so shocked, so elated.

something religious, a kind of complex,

it will get lighter

, something washing, cleansing, revealing, etc.
