OK. So Everard has lost his innocence but innocence still exists, in this case represented by the new Time Patrol recruit, Wanda Tamberly. Everard thinks:
" - Afterward, let him get on with his life, and she with her new one in the Patrol." (p. 7)
- which is what they do until, after a while, she asks him for help... Does Wanda lose her "innocence" in Beringia? It will be necessary to reread a few passages in that chapter.
Meanwhile, however, Everard, intent on pursuit of the Exaltationists, realizes:
"...that what he needed was not surcease but the completion of the hunt." (p. 8)
Not innocence but completion of the task at hand.
