"The 100" has been on the brink of a war for a couple of episodes now, but the upcoming Season 3 Episode 7 might finally see one, considering Heda Lexa (Alycia Debnam-Carey) will learn about the Arkers' latest attempt at breaking the Grounders' truce. "Thirteen" will also reunite Octavia (Marie Avgeropoulos) with Clarke (Eliza Taylor).

In the previously aired "Bitter Harvest," fans had seen how Pike (Michael Beach) commanded his soldiers to evacuate a village of Grounders and give Lexa yet another reason to reevaluate her new "blood must not have blood" motto. Although the village was burned to the ashes, Octavia's warning had given the villagers enough time to evacuate.

However, instead of thanking the younger Blake sibling, the Grounders held her captive and bombed the village with a poisonous gas when the sky crew came in. In the upcoming episode, Octavia will be taken to Lexa, where they will reveal how Sky Crew is abusing the commander's patience.

The episode is also going to have flashback that will give viewers a glimpse into the apocalypse and show how the world of "The 100" came to be. The viewers will get to the see the events on earth from the vantage point of those in the Ark.

Meanwhile, there is a rumour that Ricky Whittle, who plays Lincoln on the show, might be leaving soon. It comes from none other than the actor's mother, who posted on Twitter that there is some bullying going on in the sets of "The 100."

Neither Ricky nor Rason Rothenberg, the creator of the show, have commented on the accusations yet. It is understood that mommy Whittle is visiting Ricky in LA when she had a hear-to-heart with her son and learnt about the bullying in sets of "The 100."
