During the second season with the Moose, which person shows up at a game from Saul’s past? What is Saul’s reaction as this person drives away?

There is a warm meeting between the two but it is tempered with hidden trauma. Father L. is happy that Saul is making it at hockey and Saul is happy to see Father L. Saul however has mixed feelings because of the abuse that we find out about later in the story. We never see Father L. again after this meeting: his presence remains a ghost that haunts Saul until the end of the book.
