Tarn lets Drift pull his leg away as he stops just outside the city. Its not like he can go anywhere. And with his swords left far behind he is basically useless against Tarn.

"Now, Drift, I'm afraid I have some good news and some bad news." He kneels down, clapping a hand on his shoulder as Drift braces himself on his hands. "The good news is that I'm not going to kill you. Isn't that nice. That bad news is that by the time I am done you..." He buries his fist in the dented plating of his stomach again, " Well, you will wish that I had."

Kneeling on Drift's good leg, he leans in so that their faces are just a hair away. "You see, I have use of you. You are going to help me with a little task."
