Malleus was going to be a strong leader, with a powerful will. Lilia knew this. Believed in him to do what was right, to persevere through and believe what he wanted to. What was right. Here, bringing him to this school after Malleus received that letter, was the way to do that. To help him branch out from the closed mindedness of those who would teach him otherwise.

Those four little words are too sweet. Like sugar mixed in honey.

"... and you know very well what it is I want." Lilia tells Malleus, keeping his words simple, clear yet still just vague enough to not be obvious. To let Malleus come to his own conclusions. That's the way to do it, after all.

Otherwise, he may say something that frustrates the prince. Makes him think twice about wanting him around.
