Darius makes it clear here that the trip to Yazd has been many things, but it’s mostly been a time for Darius to discover how to feel his feelings and be emotional around his family members. Now, Darius puts this into practice when he doesn’t just accept Babou’s kisses—he actively hugs Babou and says “I love you” of his own volition. In their parting moments, Darius is doing his best to show his grandfather that he loves and cares for him, something that Darius seems to hope will make them both feel good and valued.
