Honestly, it's lucky as hell these two happened to be nearby if he's this attuned to following smells, and for the first time in a while, new determination that they might actually track down the killer this time flares in him.
While Shun doesn't know what the swapping cartridges signifies, he can see the faint traces of what appears to be cheetah-like features appearing, and clicks to what that means with enough time to be ready to have to keep up. As soon as Ken takes off, he's following - while Shun's speed certainly isn't superhuman, it's impressive for normal human levels, and he figures right now it's fine if he just keeps Ken in sight rather than even attempting to actively keep up with him anyway.]
