IN: It 's Doctor Who , anyone can come back , anything can be undone , if Rose can come back from another dimension , the Master can survive the Time War and the Daleks can keep escaping certain extinction ... they can get around this plot point should it ever serve them .
what is the reason anyone can come back and anything can be done ?

OUT: Doctor who is a fictional story where time travel and almost anything else is possible .

IN: It felt appropriate , if depressing , that I would be the one . With more sadness than hope , I was prepared for the journey , which would take many days . We had to live out of sight of them of course , or risk extinction . We had gradually moved farther from the caves . It would take 5 - 7 days and nights of walking to reach them .
Why does the speaker view the upcoming journey with more sadness than hope ?

OUT: They will have to leave their home for good and the situation as a whole is pretty grim and uncertain

IN: So there I was , walking one of my employees out to her car at the end of the night , about 11:30 . I glanced up and happened to see ... a deer . Not unusual in southern Kentucky , but this deer was walking across the parking lot of the Dollar Tree next door . It 's a big parking lot .
What may happen if he did not walk his employee to her car ?

OUT:
He would not have seen the strange sight .
