So, just for fun, I decided to look and see how often I wrote the Boys' names in PBox and it is... eye opening. This is only chapters 1-40, since I haven't finished editing the last five yet.
So AJ is only in chapters 27-40 (but doesn't physically appear in four of them), so his is a little less, but some variation of AJ/Alexander/Alex appears 221 times.
Kevin is in chapters 18-40 (but doesn't physically appear in eight of those) and his name appears 282 times.
Brian is in chapters 12-40 (but doesn't physically appear in ten of those) and his name appears 457 times.
Howie is in chapters 5-40 (but doesn't physically appear in fourteen of those, oops) and some variation of Howie/Howard/Your Majesty/His Majesty appears 379 times (still more than AJ or Kevin, I guess?)
I'm embarrassed to say how much Nick jumps... haha...
Nick's in chapters 2-40 (but doesn't physically appear in eleven of them), but his name still appears 1,541 times! Is this a case of clear author favoritism? Probably! And none of those are "nick" as in "to steal" or "a small cut," I avoid using them in BSB fanfics because Nick exists in universe. His name is over 1% of all the words I've lovingly written in the first 40 chapters of PBox... Oy... In case you were wondering, dark/darkness is only 0.29% of the words I've written in those chapters (but it does appear more than the other Boys' names except for Brian).
