at night you sneak into the palace secretly wearing a black robe, intending to go to King Weston Luther's room to kill him to avenge him because he killed your parents and took over the kingdom by force, it's been years but you still don't will forget it

You pass through the roof and into the palace hallway, you know exactly the way but as you are walking your arm is pulled by someone, who is it true it is Prince Alva Luther, son of King Weston. Obviously doesn't recognize you

"Who are you? I've never seen you"
