After Ethan trained Luca that morning, he felt bad knowing that he was dripping with pheromones but it wasn't something he could help. He didn't want to be on suppressants that blocked his pheromones from helping Sophia develop her own, and he never wanted Sophia to ever have to experience the side effects of suppressants.
The omegas and alphas around them would have to be annoyed with them for at least a couple of days out of each month until they mated to one another if they ever did. However, it was something he would never force her to do.
After going through meetings all day and lunch with partners regarding a deal he had been working on for quite some time, he didn't even think about his promise to find Ethan suppressants until the end of the day.
