I was referring to the Duffy from "Hollow Pursuits," who became a regular character in the SCE series. And the fact that Duffy wasn't a primary character in the canon is irrelevent, because the issue postulated was not whether or not Trek Lit has a tendency to bring primary canonical characters back to life, but whether or not Trek Lit has a tendency to bring primary characters in general back to life. Corps of Engineers is a regular, ongoing TrekLit series, so the creative decisions made in that series with regard to its primary characters are as relevent as those made in any of the post-series continuations of TNG, DS9, ENT, or VOY.
