>>213453454It's really not small at all, Igor winds up being a mirror held up through which we understand Anora better, all those scenes in the second act are important. He's in a similar situation to her both professionally and personally, only differing in demeanor, which she doesn't notice, but their commonalities are made quite clear. Even from his very first scene, he's not even introduced by name, he's just called "the Russian", same as they never call her Ani, just "escort" or "whore" or "her" and frequently speak as if she isn't even there. Igor is the one that actually sees her.
