Ryland Grace’s reaction when he opens Rocky’s xenonite container might seem dramatic, but there’s a very good reason behind it. The container exposes him to concentrated ammonia, a substance known for its incredibly harsh smell and its ability to irritate the nose, eyes, and respiratory system. Imagine the strongest cat urine smell you’ve ever encountered, amplified to an almost unbearable level. That’s essentially what Grace experiences. What makes the moment even funnier is the difference between Grace and Rocky. Rocky doesn’t experience odors the way humans do, so what feels absolutely unbearable to Grace is completely normal to him. Meanwhile, Grace is left dealing with the unpleasant reality of opening a container filled with ammonia.
