Critical response Michelle Erica Green reviewed the episode for TrekNation, and was concerned by the continuity issues that the events in the episode presented, such as why Captain Jean-Luc Picard of the USS Enterprise (NCC-1701-D) didn't have a record of Archer and the crew's encounter with some nameless technologically enhanced aliens who assimilated people when he met them for the first time in "Q Who".
