At only 5C (41F) out, it's a bit chilly, and Rin reluctantly starts a campfire. (A narrator gives useful tips.)
When night falls, Nadeshiko appears, seriously freaked out. She fall asleep after biking out here and is too afraid to go home at night.
Rin gives her some food.

She does remember her sister's number, and borrows Rin's phone for a rescue call.
Before she leaves, she gives Rin her number.
