^ You may be right about Archer, though I never really saw his character as truly consistent, but I don't exactly have any solid counterarguments either.
I disagree on T'Pol though. All through season 4 she appeared to be a complete emotional mess, at least to me. And in this novel, she had to deal with the fact that suddenly she was basically all alone ("mother, daughter, lover, all gone" as M&M's put it), and Archer wasn't much of a company since he was guilt-ridden over lying to others (especially her) about Trip's death. BTW, Archer delivering the (fake) sad news to Trip's parents was a powerful moment, at least to me.
And you mention TATV showing the end of T'pol's transition. Well, according to this book, TATV events never happened in 2161, and they didn't happen the way they did in that holodeck simulation. The whole point of TGTMD was to rewrite TATV, the episode in which none of the ENT cast really felt "in character" to me (the least of all Blalock).
