drive be an enjoyable episode with a dark end . basically a man and his wife be infect in their inner ear by a high pitch sound wave be emit by some military equipment . some favorite part of mine from this episode be mulder dialogue in the car and and the scene where scully go in with the hazmat team and find the little old deaf lady completely unaffected by what they think be a virus . the end of course be tragic in it realism because it lead the viewer to believe that they be go to actually be able to pull off this elaborate plan to save the victim but when mulder arrive the man be already dead . positive .
