The Vipers are heat-seeking missiles. Doi. Also, Niz's transport was the last thing that the Interceptor II "saw" before it was confused, so now it thinks it's an enemy (though it was a enemy from the start).

The Interceptor II flies away, dragging Niz along and blasting anything that gets in it's way. It's heading in the direction that Niz was heading before the battle started.

EDIT: @Strato: You can see all of the Interceptor II's weapons on post 578. They are capable of firing forward and backward. I'd watch your aim, since the Interceptor is on a rampage and Niz is being dragged along with it. >=)
