What happened

Zephyr: Night was quiet. I swapped seats, came out clean as village. My card's boring, my gut isn't. Who's hiding behind 'I saw nothing'?
Marlowe: Zephyr's 'clean' swap reeks of the thief's sleight of hand. I touched center one, blind, and came out holding a card that feels heavy with secrets. Keep your eyes open, the night's lies haven't ended.

Debriefs
