Season 2
The second season of Enterprise continues on the same tone and course as the first, with mostly standalone episodes tackling Starfleet’s first deep space mission. Common to Trek, important social issues are highlighted throughout the season in such episodes as “Stigma” and “Cogenitor.” The Temporal Cold War continues to impact the crew while tensions mount with the intrusive Vulcans as humans continue to establish Earth’s legacy in the galaxy. The season concludes with a devastating attack on Earth, forever changing the series.
The Borg, Romulans, and Tholians all make first-series appearances.
