By popping up, Lina would discover two very alarming things.

First, it could track her, even underneath the bridge. The machine had swiveled on its mounts so that as she flew up it was pointing just to the left of her -- it had gotten that far before it had to stop to charge.

Second, it was charged. The awesome, sun-nova power of the P3Wx2 vaporized the air itself as burst out of the main cannon, close enough to graze her cape. All well and good that it missed, but a moment later the mount interlocks disengaged with a hiss and the cannon began to swivel, the sustained beam tracking towards her.
