Everyone, including Kazimir, was oblivious to Empress Carolina's plans.
In actuality, Kazimir really didn't know how his Empress Mother will create trouble for Tehila. But he trusted her fully because ever since he was a child, when his mom says that Tehila and Leon will not have a good time, they really would not have one!
Didn't his Father Emperor almost not interact with Tehila except on official occasions?
Didn't Leon have to be sent to the battlefield at a young age and not grow in the castle to be pampered like a prince?
Because of this, he knew that if his mother would do something, she would really do, and just like those years, all he needs to do is to sit back and watch the great big show.
As usual, the Emperor was the first one to perform what the clergyman had instructed.
Ring ring ring!
