For me, I really appreciate how the show handles he's stutter. They dont use it as a punchline or point of pity. It just is. The sutter is also random and pops up at even in fast-paced scenes, forcing a few seconds for us to patiently wait for Viktor to finish his sentences. I'm sure most stutterers could relate to that There is a scene with him trying to order at a restaurant, and the waiter gets really impatient. The Penguin steps in and insists Viktor be given time to finish. Loved that. Also, the show doesn't try to give him a "magic cure." Because there is nothing to cure. Viktor just stutters, and that's okay I really resignated with all that and the authenticity of his character.
