For one it would depend on who kidnapped him, if gammas were involved it wouldn't have worked and also if suppressors were used. And then it's difficult to tell, Chase normaly completely relies on his bodyguards, so did it come to is mind to use his pheromones?
And Chase is also one of the weaker Millers when it comes to pheromones.
Honestly, Chase is the dominant alpha Miller who should be the easiest to kidnap, if on his own. So getting a bodyguard as a partner is a really good thing.^^

Can't Chase use his pheromones to subdue his kidnappers though? Or maybe he didn't learn that coz he's always hated releasing his pheromones.
