Perhaps it was to save his life that he didn't hesitate to give up his own cherished freedom.
Or it could be that sense of mutual dependence in an alternate world.
Booker, who had almost always been on the run, just wanting to clear his debts, finally behaved more like a tough guy at this moment.
With a leap, he plunged from the mansion halfway up the hill, reached out with his grappling hook to catch the monorail, and began his pursuit of the Nightingale in mid-air.
Unfortunately, the Nightingale used the same trick again to destroy the monorail and robbed Booker of his ability to continue the chase.
Back on the ground, Booker resolutely continued the pursuit, only to be enveloped by a strange glow as he ran with wide strides.
The next moment, the light vanished.
He was still in the same place.
But the scene around him seemed different.
Although it was still the height of summer, snowflakes as big as goose feathers were falling from the sky.
