Estefan wanted to follow his master as he was aware of what Cassius was capable of in his state, adding on his thirst for blood he was dangerously close to losing control. However, he couldn't leave Esme alone so shocked, for any human being exposed to Cassius' energy for too long could cause corrosive long-term effects that was if the person got out alive. Esme continued to let out cries of fear 'I just wanted to be of use to you, I promise I'll follow instructions properly next time' she continued to cry.
As much as this pained Estefan this told him that she could still breathe which was a good sign. 'No, it's my fault I sent him to you when he was already in a sensitive position, I didn't get the chance to brief him' he was frustrated with himself for putting Esme in a dangerous environment. To make sure Esme was unscarred he kissed her forehead further releasing his pheromone to comfort her and absorb any leftover toxicity in the air.
Every vampire's pheromone varied in traits and qualities and Estefan's was one of a calming nature with healing properties. Of course each type of pheromone would vary depending the vampire's emotional and mental state and who they were using it on but it still had an underlying nature. In contrast Cassius' pheromones were one of extreme properties, whether that was of pleasure, suffocation or rage, any emotion would be amplified. This was ironic as Cassius was the opposite and usually felt hollow inside.
Once Esme showed signs of stability Estefan suggested she wait in his quarters in the west wing as he had a feeling things were going to become intense again. 'Okay but come see after, I don't want to leave you with a sour taste in my mouth' she smiled playfully telling Estefan she was more than fine.
'Of course, that smile could get me to do anything for you' he replied while giving her a loving peck on her parted lips. He picked Esme up from the floor and in a few seconds, he had traversed the central area of the mansion back to the west wing and laid her down on the bed giggling.
'You know exactly how to cheer me up, I love it when you use quick step with me. Makes me want you so much more.' Esme stretched out on the bed in seductive manner pulling Estefan in by his tie. Estefan almost giving in replied 'I promise I'll make it up to when I'm back' he unwillingly got up and left a desperate Esme alone.
Quick step was a skill that all senior vampires could use, it was how Estefan managed to always reach his master on time. Each user would activate this skill in their own creative way and its speed varying on the vampire's power level.
Fixing his tie Estefan was now visibly irritated which was not the norm for him as emotions did not easily show on his face, but Esme was a special case.
