I'd seduce him, make him fall in love with me slowly. Be taken out for dinner. Smile innocent at this slime. Invite him to the river. Bag is prepared there. Ask him to look for the ring i dropped. Approach from behind. Hit him with pan from that bag. He collapses. I grin. Drag him half into water. Cut his hair off. Tie his arms and legs together. Add "some" stones in pockets. Bid farewell to him. Let him drown.
