Note: Full spoilers for the episode follow. 12 Monkeys began its three-part season finale with the eventful and emotional "Resurrection" which saw several important characters die, one character come back to life (kinda) and the pivotal relationship between Cole and Cassie revived. How permanent some of those deaths will be depends on whether or not the destruction of the time machine can be undone by Cole and Cassie's now last-ditch effort to stop the paradox of the mysterious primary in 1957. Jen has known the date of her death since she read it on the Word of the Witness map.
