"Um... ah... yes, hang on..." One of his serious-looking officers passes him a file. "Take a look..."
Seems Vil uses very specialised, small bombs. They are so small that they bypass security sensors, which is how she gets them in. BUT they have no room for a decent trigger machanism (which would be detected by the sensors anyway).
Instead, they are remote activated- but the activator only has a range of about 100 yards. Vil will have to be close to his target to hit the kill switch.
BTW, small they may be but one would leave little of Mah or his pod.
