Maybe they're set, but the motives on both ships conflict. You said you told your crew that if neither ship killed, both ships would survive. Here we were told that both ships would be purged if neither ship killed. So if none of us killed—what would happen? These motives can't both be fulfilled, right?

[ Maybe? He looks at Luke helplessly. They're definitely failing here and it's stressful. Sunny take pity. ] Putting on immunity has already messed with one part of our motive, anyway. If both ships had a kill, we were told we'd all continue. The immunity wasn't part of your motive, right? Like Luke said, you can take that off. All we want is something to make both the motives on the ships work.
