Was that directed at me? I did read the thread, I was just contributing my two cents into the debate.
As for your specific complaint, of course I can rationalize V not memorizing another flight spell:
He wasn't thinking clearly and presumed that the flight spell that he already had up would be sufficient. Should V have memorized more? I suppose so. But V hasn't exactly been known as a good tactial planner, now has he?
Sheeesh. All this drama over a ficitional character not memorizing enuf flight spells
