Paradox

The Corridors Of Time.

Brann captures Storm and Lockridge.

Brann tells Lockridge that he, Lockridge, will defect from the Wardens and will come to tell Brann where to go to capture Storm and himself.

Lockridge escapes and brings Wardens who capture Brann and rescue Storm.

Storm asks Lockridge to pretend to defect.

What would happen if Lockridge refused? He remains loyal to Storm and does not refuse. If Lockridge were the sort of person who would have refused, then this sequence of events would not have occurred.
