How did season two end?

For those who need a little recap of how Silo season two ended, Juliette made a surprise return to the Silo, but as she re-entered she was met by Bernard, when they were both engulfed in a huge fire in the airlock.

Just as their fate was left hanging in the balance, the next scene showed a flashback to the Before Times in Washington DC in the darkness, and pouring rain. Congressman Daniel Keene (Ashley Zukerman) is seen arriving at a bar, where he has his radiation levels checked by a doorman, before sitting down and chatting to a journalist Helen Drew (played by Jessica Henwick).

Congressman Daniel thinks they're meeting for a date, but it's soon apparent that Helen has a different agenda, as she asks him about the dirty bomb that was detonated on US soil, and if America will retaliate. Daniel also gives Helen a Pez - which Silo fans will know has had significance throughout the series.

Here we take a look back at each of the season three episodes...
