Leave your apprentice where he lies, you'll come back to him later, and continue your work on Queen Amidala.
From Create Your Own Story
You turn your back on Obi-wan, deactivating your lightsaber. Amidala still squirms on the ground, fresh tears flowing from her eyes. "Please," she begs, looking up at you. "Please, no more."
You simply smile as you begin shocking her again. Fresh screams pierce the air. You are enjoying yourself, feeling powerful. A new sensation begins to come over you. Lust.
Just as you are about to stop torturing her and act on those lustful thoughts, an immense pain erupts in your back and chest. Looking down, you see the blue blade of a lightsaber protruding from your chest.
You can hear Obi-wan whisper behind you, "I'm sorry master."
