Zoltan couldn't climb the rope so easily and he hesitated several times on the attempt either landing not so gracefully on the ground or winding up unable to pull himself up to begin with. Why in the wide world would someone even choose this route when a simple door would do just fine? Why even stray off the escape course  when there's no surefire means of escape with your own idea? Hence Zoltan asks a very obvious question<strong>"Do you have ANY idea what you're going to do after we get on the roof??"</strong>Zoltan sounds highly irritated when he finally does manage to climb up.
