Feather Song's speed of escape could be described as nothing short of rapid...
Thanks to the Talents of Blessing of Shadow, the despondent girl, who thought her end had come when she was caught by Billy, triggered 'Stealth Level +3' and 'Force Quit Combat' during her fall, instantly disappearing with her high Stealth Level of 7, and then scrambled out of the room and fled Pink Magpie Court without looking back.
If one were to simplify the sequence of events...
First, after Feather Song was captured, Motan, believing himself to be exposed, drew his blade and furiously stabbed Jerman.
Then, Billy, attempting to negotiate with Motan, used Feather Song's life as leverage, demanding that the former spare his life.
Next, Feather Song, knowing she wasn't allied with Motan, felt utterly hopeless, and promptly forced herself to recall yesterday's big sale at the mall, thereby failing to trigger Blessing of Shadow.
