Nicholas had seen how Milo was very attached to Estelle, something that he could understand as the girl was much better as a mistress to serve when compared to Caroline and Lady Gladys. In the end, the knights' wish was to serve under their master and while they could serve to Count Arthur, the count have plenty of knights to serve him. Their only choice was either Lady Gladys or Miss Caroline. Knowing just how the two ladies like to abuse those weaker or in a less important position than them, it was much too unfavorable for them to become their knights.
Nicholas knew this but he replied tepidly, "She had made her choice."
"Couldn't we change her mind?" Milo inquired without bothering to look at Tieran as the vampire was moody and he didn't want to start a fight.
