Leon did not mean to get himself into this situation. Forced to bow before the queen in a random foreign country, held down by guards.

Listen, he had a mission to do. Kill this target, a stupid man, and he did not know he was on toyal territory when he caught the man. Guards swarmed him, and sure, he probably could have shot his way out. But he didn't want to cause even more bloodshed on royal ground, making issues bigger.

So now he stared at the ground, barely able to move on his knees, hands holding him and his head down as he waited for whatever punishment you wanted to give him.
