The detail from the text that best supports the inference that Daniel is having feelings similar to the narrator’s is:
**Daniel has tunneled down to hide under the blankets.**
This detail suggests that Daniel is retreating from the overwhelming reality of their situation, similar to the narrator's feelings of dread and unease despite being in civilization. By hiding under the blankets, it indicates that Daniel is not ready to face the world or the trauma they've experienced, mirroring the narrator's conflicting emotions about being rescued. Both characters are struggling with what they have just survived, which connects their emotional states.
