Pretty sure I might know who SM is talking about, but I won't say. All I'll say is... the character did sort of have a first name before, but never one that was officially confirmed, just inferred, and this book now changes that for a new one.
One goof I have noticed in this book - Vriess' character bio on the Betty crew page says he died on the USM Auriga, when he clearly didn't. It's not even a case of in-universe mixed-up or incomplete info on the part of the report writer, because a little later it mentions that he survived the incident! Whoops
In fact, the book also gives Vriess' first name as Dom, when the novelization of the film calls him John. It's a bit strange as the other
Resurrection first names in the report tie up with those that were given in the novel, and a bunch of other book-only stuff is mentioned (like Kawlang).
