A question I often asked with Green Lantern, so I'll ask here as well as it relates to Betsy: Why a gun and not a grenade? Why a grenade and not the psionic equivalent of an electromagnetic pulse with a wide area burst radius that only harms the enemy? Being that she's a powerful telepath it wouldn't be difficult for her to do. So why just a gun?
And when did Betsy become familiar with assault weapons in the first place? Just curious.
