The effects of Jaha's (Isaiah Washington) City of Light chip will be tackled in the next episode of "The 100" season 3.

In the trailer for the episode titled "Bitter Harvest," Jasper (Devon Bostick) asks Raven (Lindsey Morgan) what she took to alleviate the pain that has been bothering her for a long time. She then tells him to go to Jaha to get one of the chips that she took.

Executive producer Jason Rothenberg talked about the effects of the chip on Raven in a sneak peek at episode 6. "For the first time, she's not in pain and that's amazing. It's really actually awesome to see Raven finally feeling good," Rothenberg said in a video posted on the show's official Facebook account.

Rothenberg also mentioned that Raven will be willing to do anything that Jaha will ask her to do, including getting orders from A.L.I.E. (Erica Cerra).

"A.L.I.E. has a job for Raven and that is one of the reasons why A.L.I.E. came back to Arkadia first was because the computer system in Arkadia, A.L.I.E. believes contains something that she's looking for and she is going to ask Raven to find that thing," the executive producer revealed.

The promo video for the episode reveals that Abby (Paige Turco) will try to find out if there will be side effects upon taking the chip.

Rothenberg also teased that in the upcoming episode, Pike (Michael Beach) will continue to take advantage of his new powers. However, Kane (Henry Ian Cusick) will do everything that he can to stop Pike from abusing his title as the new Chancellor of Arkadia.

Meanwhile, the episode will also reveal that Clarke (Eliza Taylor) and Lexa (Alycia Debnam-Carey) will receive an unexpected gift from the King of the Ice Nation Roan (Zach McGowan).

The upcoming episode of "The 100" is slated to air on Thursday, Feb. 25, on The CW.
