Maybe Drift is lucky that Tarn crushed his vocalizer so early in the fight -- he can't let out a pained cry when Tarn dislocates his leg, only a crackle of static. It pretty effectively immobilizes him, because even with the use of his arms, with no swords and Tarn dragging him across the ground, out to the far reaches of the city. Drift's spark quails in his chest despite himself; the farther they get from the center of the city, the less likely it is that anyone will see what's happening.

Then again, that might be a good thing. Drift hadn't expected to come out of this alive, anyway. Maybe if Tarn pulls him away from the city, he can get a few last desperate blows in, incapacitate Tarn -- so he doesn't resist as Tarn drags him for what seems like hours, even as every circuit lights up with pain. But as soon as Tarn seems to slow down, Drift grits his teeth and braces both palms on the ground, trying to use them as leverage to twist his body and pull his good leg out of Tarn's grip, although with his other leg hanging uselessly from his hip, there's a lot of dead weight.
