The 100 arrived on UK screens earlier this week and it was the biggest ever launch for E4 pulling in 1.3 million viewers.
The sci-fi drama, which has already been renewed for a second season, tells the story of 100 young offenders who are sent back down to earth to see if it is inhabitable following a 97 year exile. In the first episode we were introduced to central characters Clarke (Eliza Taylor) and Finn (Thomas McDonnell) and the scene was set for a Lord of the Flies meets Lost type scenario.
The episode drew to a close with a shock when Jasper (Devon Bostick) was speared indicating that there are already people living on earth.
The second episode of the season is Earth Skills. Having discovered that Jasper may still be alive, Clarke leads a rescue party on a mission to locate him, but the group are shocked at what they find.
Tune in to E4 at 9pm on Monday to see the episode. Preview it with our gallery below:
