12 Monkeys Season 2 Trailer: Cole and Cassie Are Reunited in the '40s

12 Monkeys is time trippin’ to the World War II era in a new trailer for the Syfy thriller’s second season (premiering April 18).

But rather than battling the Axis powers, Cassie — who traveled to 2043 in the Season 1 finale — and Cole meet up in the past to stop the titular, nefarious organization, which is using time against itself.

“If they succeed, all of humanity will collapse into itself,” Jones warns.

One thing that apparently doesn’t change, no matter how much you mess with history or the future? Jennifer is “a pain in the ass in every time period,” Cassie laments.
