The Pressure's on During Tonight's 'The 100'

Octavia (Marie Avgeropoulos) looks a little worried in this still from tonight’s all-new episode of The 100.

In “Contents Under Pressure,” Clarke (Eliza Taylor) and Raven (guest star Lindsey Morgan) make contact with the Ark, and Abby (Paige Turco) guides Clarke through a dangerous procedure in a desperate move to save one of their own.

Meanwhile, on the Ark, Abby is removed from the council, and former Chancellor Diana Sydney (guest star Kate Vernon) takes her place.

Jaha (Isaiah Washington) reveals to Abby that there are not enough drop ships for everyone on the Ark to go down to Earth, and Kane (Henry Ian Cusick) begins to deal with his guilt over his recent decision.

“Contents Under Pressure” airs TONIGHT, April 30 @ 9PM on The CW!
