Q couldn't say 'the J word' or the 'Z word' could they?

Not only would that be buried as 'anti-semitic', but it isn't entirely accurate as the word has little definition today that can be surmised without problems.

So they save Is-Ra-El for last.

If they were dwarves you weren't allowed to count, you just remove the non-dwarves and now it's pretty obvious, no 'count' needed. Wow....look at all the dwarves.....

That's why you remove others first....and save the Hall of Durin for last because that's where the demon leader the Balrog lives. (Since we're watching a movie)
