"But...a corpse..." Well, it's magic, obviously. Kyle watches her with an expression that nicely conveys his disbelief. "Why, exactly, would someone want one of those...?" If they're slow, and easy prey for a sniper or reasonably accurate shooter, they aren't so much of a threat, right?

"Planes of existence...?" Oh, that kind of plane, he realizes. Like the coordinate plane. He's done maths involving a number of parallel or intersecting planes before. The guilty look is filed away for future reference. "Well, you never know. An explosion big enough might..." And that's enough of that, before he's tempted to try it. "Silence is usually the best way of allowing knowledge to die out," he agrees, a little grimly. He knows that all too well.
