One's subconsciousness was the most private thing one could have. In that sense, Lucas was taking a big risk in approaching Elysia.
She likely had secrets she did not want to share with Lord Lucas and the man would try his best to respect Elysia as much as he could.
But he had to recognize the underlining truth behind his actions as well. He was a selfish man who would do anything for his goal.
"Lucas, you are taking a big risk. Death is inevitable if you do that but if you fail then you will die immediately."
Lucas heard those words with one ear and let them out with another. He knew the risk of what he was doing pretty well so Sorias did not need to remind him of this.
"Lucas, I am sure there is another safer way to do this. You don't have to make the same mistake my brother made a long time ago."
Soria was a persistent beast. He was like a brother Lucas never had and the term also fitted well with the current relationship they both shared.
