However, although there is no single standard of grammar that is universally accepted (as I found out by using "gotten" in a B7 fic), there are objective standards that can be consulted, there is something close to one view of what Character X is Really Like per fan, and nothing to check it against. It doesn't work to say "check it against canon" because of the familiar phenomenon of everyone having zir own idiosyncratic set of tapes.
