Everard And Varagan Through Time

OK. From Everard's point of view, the case involving Stephen Tamberly occurs between his own two meetings with Merau Varagan but does Varagan experience these three cases in that same order? Not necessarily.

Raor says:

"'This is remarkable. I do believe you are that same agent my clone mate spoke of, who almost captured him in Colombia.'"

-Poul Anderson, The Shield Of Time (New York, 1991), p.117.

Everard replies:

"'And almost in Peru, and did in Phoenicia...'"

-ibid.

That still leaves the possibility that Peru was pre-Colombia for Varagan. Maybe it does not matter in this case but we should always remember that these characters are time time travellers. A Patrol agent could kill a Neldorian, then, at the end of his own world line, be killed by that same Neldorian.
