I was hoping for subdue as a step 2. If Jacen thinks he's a Vong God now then he'll fight like a Vong won't he? Now that we know Anakin and Jaina definitely haven't been swapped out by the seal and we can all be prepared going in, I'm all for subduing.
...maybe I'm being a little on the cautious side here for once. It's just, they look exactly like my parents. If there could be one time where we went in prepared enough that no one on either side got seriously hurt I pick this one, you know? But I understand that goes out the window a little if they make a move towards actual killing.
