Needless to say, Mycroft wasn't thrilled with how Will had decided to play games with him. He had expected it to some extent, but that did not mean he had any desire to embrace it. Still, it seemed as though it had been inevitable. Considering that, he supposed he was grateful that in this particular scenario, the nonsense had been kept to a minimum.
"To some extent, I would say you still are a disobedient prince, and should a situation arise where I risk falling into disarray, I cannot claim I don't believe you wouldn't watch events unfold with great amusement, perhaps even encouraging me along the way. However, I am pleased to hear you confirm that you are not actively seeking my downfall."
The development between them continued to feel beneficial. Mycroft far preferred everything to be out in the open, especially when Will was not actually seeking to cause any major problems. And really, what was a little mischief in the grand scheme of things? A certain level of it could be brushed away with no consequences, and considering his reputation as a dreadfully dull young man, Mycroft believed he could ane any other problems on the other prince and great away with it with little more than a light scolding. Not that he wanted to do such a thing, of course. He held no ill will towards Will, and he'd always been incredibly keen to avoid a telling off of any kind, no matter how minor it may be.
Besides, the nonsense wasn't new. Despite his own avoidance of it, Mycroft's family liked a little mischief - the King included! It was to be kept behind closed doors, though, and official business was not to be disturbed.
"I must keep you away from my youngest sister," Mycroft informed Will. "She is a troublemaker. If you are only aiming for the inconsequential, then I fear she may become a bad influence on you and cause you to drift in a direction you were hoping to avoid."
They would get onwell, Mycroft thought. Potentially too well. Even if it were only some kind of partners in crime arrangement, the risk of trouble was far too high for his liking. The two of them needed to be kept apart, even if excuses has to be created to make that possible.
His other sister, at least, was more sensible, but could still be corrupted to some degree. Mycroft would not worry about her meeting Will, not would he worry about the other man meeting his parents. It'd presumably happen at some point, what with them wanting to be polite hosts, but likely not for a while. They were currently busy, and they would also be waiting for Mycroft to report back that Will had settled in nicely before they found time to visit.
