Tiberius had been in the middle of something when Antigone burst in, but it wasn't anything terribly important, which was why he hadn't bothered to lock his study door in the first place. He was mildly annoyed as he shoved the book aside, but willing to listen to her. Her chosen topic was rather unexpected, however. Truth be told, the plan was not progressing as intended. Cassius was, perhaps predictably, not very good at attracting the attention of a potential wife, and there was only so much pressure that Tiberius could exert from his position outside of the immediate family. Lucius might have been prevailed upon to arrange a marriage, as he had done previously, but he had other sons to consider, and one unmarried daughter who would very quickly become a higher priority.

That being said, he had hardly expected any criticism to come from Antigone on the subject. As long as he wasn't threatening to murder her in order to get on with the process of selecting and procuring a new bride (which he had not so much as mentioned since their initial agreement), what business was it of hers? It wasn't as though he needed anything from her in order for the plan to progress smoothly. He certainly didn't need help, and was hesitant to reveal many of the details of the plan lest she think that her interference would be welcome.

"Enough, for the moment," he responded curtly. "Why?"
