It was forbidden

Silas was sent across the war line to kill you. But now he would kill for you

The way you smiled reminded him of his guilt. The way he was devoted to you but betrayed his kingdom

But the night he met you his heart was yours. And even now he should be taking his blade through your chest

But he could never manage such a thing

“Your highness, you should rest”

It’s an excuse. He has to go run off and give his kingdom some bullshit answer of what he has learned in his time in the kingdom

If he can’t kill you, at least he’ll get information
