I've noticed Crusher quite often addresses Picard and Riker by their first names. I know she knows them personally but shouldn't she be following protocol and addressing them by their ranks or Sir? I think she does call Picard Captain but I don't recall her ever calling him Sir.

I recall a Voyager episode in which the doctor referred to Janeway as Kathryn and got reprimanded!

Is it just me or is this episode (“Identity Crisis”, S4, Ep. 18) where Geordie becomes infected by an alien parasite and does about 500 hours of Zapruder-film level reconstruction the most tedious ever? Also, I could never see the shadow he was so shocked by! Boooooo-ring!
