After Diyoza's (Ivana Milicevic) little care package led some members of Wonkru to defect on The 100, Octavia (Marie Avgeropoulos) and Bellamy's (Bob Morley) relationship has been strained, to say the least. It looks like Bellamy just can't get on board with this new, darker version of his baby sister.

The mounting tension between them is more apparent than ever in this exclusive sneak peek at Tuesday's episode, "Acceptable Losses."

While he waits for news about Echo (Tasya Teles), who has taken a huge risk infiltrating Diyoza's ship, Octavia checks in for a progress report. When she sees how angry Bellamy still is about the traitors she killed, she promises that the dire circumstances are the only reason for her harsh rule and that things will get better when they get to Eden.

Suuuuuuure, Ocatvia. Totally believe you. Bellamy is pretty skeptical, too, since that's exactly what they said when they were up in space. "Then we found you," he says, not very kindly, and you can practically see the light drain out of Octavia's eyes.

Ugh, is there anything worse than watching the Blake siblings at odds?

The 100 airs Tuesdays at 9/8c on The CW.
