"[…] our understanding of each other had reached that sweet depth where two people communicate more often in silence than in words" (12.4).
This makes us believe that perhaps Holly and the narrator really do develop a true friendship. They reach a level of comfort that only true friends achieve.

"No, idiot. This is serious. Look at me. […] You might have been killed" (13.25-13.27).
After the horseback-riding fiasco, Holly displays real tenderness and concern for the narrator – she actually cares for him. And this is a touching moment between the two that shows us that Holly is indeed capable of friendship.

"It makes me furious, the way these wretched people keep persecuting him. He's a sensitive, a religious person. A darling old man" (14.2).
Even after Holly is arrested for associating with Sally Tomato, she refuses to believe that he's the horrible man the newspapers are making him out to be. Is she being naïve? Perhaps. But she might also just be displaying the loyalty she feels toward the people she believes are her friends.
