Thawne appears to have all memories of the different timelines including the pre-Crisis and pre-Flashpoint timelines, including the knowledge that Barry and Iris were married and that he killed Iris in that timeline.
Multiplex is erroneously referred to as "Dayton" Black in one caption, it should be Danton Black.
