Does a 'mention' count as a 'sighting'?

Approx two weeks ago, "The Enterprise", the latest-to-be-produced
Star Trek, had two characters marooned in a shuttle where they were
in need of some navigational assistance. One asked the other "Where's
your sextant?". The other replied "I must have left it with my slide
rule" (Both quotes approximate)
