Difficulties In The Details II

I had an uneasy feeling that the discussion did not make sense in the previous post. Sure enough:

Everard is in a timeline where two men entered a treasure house and did not exit it and then the house was found to be empty;

the Patrol puts the two men back in the house a minute or two after they had been kidnapped by time travelers so the two men do now exit the house.

According to my way of looking at it, putting the two men back in the house generates an alternative timeline in which they do exit the house but does not change the fact that Everard himself is in the timeline where they did not exit it. We can think of various complications beyond that point but I will leave it there for the time being.
