Final answer:
Kerouac's use of 'already' implies that everything has happened by now, indicating a sense of inevitability or established progression in the narrative.
Step-by-step explanation:
Kerouac's use of "already" as a transition suggests that everything has happened by or before now, implying a sense of inevitability or that actions or events are set in motion and cannot be undone. In literature, such transitions can indicate a progression of time or the culmination of events that are unfolding as expected.
The passage you provided seems to take place in a moment of transition, where characters are moving across a landscape, and there is a recognition that certain phases are completed, paving the way for the next. The use of "already" places the focus on the temporal aspect and the flow of events, suggesting that we are catching up with a narrative in progress, highlighting the immediacy of the experience.
