Cassandra Loren uses a Time Portal to travel from 2155 back to 1978 and make herself a fortune in a time when that still meant something. Adam Clement, the Time Portal's inventor, follows Cassandra in order to stop her. He is quick to contact the I.A.D.C. (because his grandfather worked for them around the year 2000) and Diana Prince in particular. Written by

Adam refers to a nuclear apocalypse in 2007, but the actions in this episode may have changed that chronology. Cassandra complains that Wonder Woman is also active in the 23rd Century, indicating Diana is either extremely long-lived or has been succeeded, although the closing scene implies she expects to be around in 2155. At one point, I.R.A.C. is about to disclose a secret to Adam, potentially its conclusion that Diana Prince is really Wonder Woman, but they're interrupted. See more
