Comments of chapter undefined of Behind Their World

This story has a nice idea. But I think the pacing is too fast for me to follow and too many points of view. And do five minutes have some significance in this story? Is it their standard waiting time? Maybe it is only me but it's too long., And I think if Leo can convince the girl to talk with them, he should not have left Darren in the first place. If Darren is so important to him, why leave him in a dangerous place?
