The Page is the young Syrian's best buddy—he's always looking out for him. He tells him again and again not to look at Salomé, in the same way that his master, Herodias, warns Herod against doing the same thing.
When the young Syrian kills himself, the Page is pretty messed up about it—gushing about the beauty of his voice, and talking about the gifts he gave his friend. When he that the Syrian, "was my brother, and nearer to me than a brother," you get that his affection maybe wasn't just of the brotherly variety (67).
Ultimately, he blames the moon for his friend's death.
