what happens at the end of Hand of Fear?
At the end of "Hand of Fear" the Doctor leaves Sarah on Earth, and she says she isn't in the right neighborhood and walks along the sidewalk.
And in the last scene she looks up.
And i wonder what her expression is. It looks like she could be frightened by what she sees. So I have imagined her seeing a flying reptile or a flying saucer or something.
Dose anyone know anything about this?
