During the last episode of "The 100" season 3 Raven (Lindsey Morgan) appeared to be getting better but the newest promo trailer for episode 6, titled "Bitter Harvest," reveals that the drug being passed around to treat pain is not as benevolent as it first appears.

Jaha (Isaiah Washington) appears to be handing out the new pain relief drug around the camp, most specifically to the younger members, stating the "chip" is merely a means of helping the community. When asked if causes any side effects or pain, Jaha simply states "nope."

Dr. Abby Griffin (Paige Turco) is not agreeing with this as she decides not to take the new drug. The trailer hints that she'll be observing several of the people who have taken it, particularly Raven, in order to test what kind of side effects the drug may be causing.

She does confront Jaha about this, stating that pain relief is not the only thing the drug results in. There are snippets in the promo trailer indicating that physical pain or mental instability may be an aftereffect. 

"The Bitter Harvest" won't focus solely on Jaha's new pain reliever as it will showcase Clarke (Eliza Taylor) confronting Lexa (Alycia Debnam-Carey). According to the synopsis from Cartermatt, Clarke will be torn between two very opposite choices: taking revenge or delivering mercy. 

At this point she is shown in promotional images to be consulting Lexa about the difficult decision ahead. While the two are not directly reconciled as they were in previous seasons, it is possible that Lexa may convince Clarke to take an action that will benefit everyone without the need of bloodshed.

At the same time, Kane (Henry Ian Cusick) and Octavia (Marie Avgeropoulos) will be working together in order to avert a possible disaster from occurring. 

"The 100" season 3 episode 6 will air this Feb. 25.
