Brainstorm doesn't really get much of an answer because Spinister's suddenly disappeared. At least, he doesn't get much of an answer until the heli makes some decidedly ticked sounding hisses from somewhere above him.

When the inventor looks up, he'll see the heli clinging to the rafters, armor puffed up so much he almost looked floofy, rotor blade so tense it was trembling and red optics round with angry terror.

It's the last he sees of Spin for a bit because he kind of just vanishes into the shadows.
