Pfeifer is trying to convince S that Corbeau is gone and tries to provide an analogous example of Ostrero being very attached with his wife and kids. S contemplates more on why he is in his journey or basically his motif for looking for Sola.
S. wonders if it is because he thinks she knows who he is, a question he has been pondering throughout his journey and finding its answer has been defined his way of life, or because he might have unintentionally fallen in love with her.
