I don't know if many of you watched the new Matt Damon movie Hereafter. Near the end of the movie, the little boy who lost his twin brother meets Matt Damon in the Book reading room, and says something like: "Hey, I know you, you are a sight[?]". Indeed, I'm missing the word between the brackets, how did he refer to a medium?
He said something like sightkey, sightkick, sightsikh, but none of these are the correct words, I've tried looking it up on the Internet but I'm truly unable to come across this synonym.
Can you help?
